-Sun Jun  7 19:01:37 1992  Jan-Simon Pendry  (jsp at achilles)
-
-	* Code cut for BSD 4.4 alpha.
-
-Sun May 31 17:28:52 1992  Jan-Simon Pendry  (jsp at achilles)
-
-	* (afs_ops.c) make sure error code is returned to user if there
-	is an immediate error in afs_lookuppn.
-
-	* (nfs_ops.c) clear out mountd port number after use.
-
-	* (nfs_ops.c) optionally (KICK_KERNEL) run lstat over the old
-	mount point.  This should go somewhere else more appropriate.
-
-Sun Mar 29 16:22:01 1992  Jan-Simon Pendry  (jsp at achilles)
-
-	* (mount_fs.c) FASCIST_DF_COMMAND is now defined as the fstype
-	you want df to see.
-
-	* (opts.c) fix buffer overrun in slash munging.
-
-	* (host_ops.c) add support for INFORM_MOUNTD.
-
-Sat Mar  7 10:23:04 1992  Jan-Simon Pendry  (jsp at achilles)
-
-	* (nfsx_ops.c) fix buffer overrun problem by allocating sufficient
-	memory.
-
-	* (afs_ops.c) fix dereference of free'ed memory when calling
-	assign_error_mntfs.
-
-	* (xutil.c) fix xmalloc and xrealloc to allow zero sized
-	allocation.
-
-	* (os-type) make it recognise aix3.2
-
-Sun Feb  9 13:14:54 1992  Jan-Simon Pendry  (jsp at achilles)
-
-	* Release 5.3 Beta
-
-	* hpux 8 support is still missing.
-
-	* (os-bsd44.h) merged in changes for new bsd nfs code.  still need
-	to add in lease and kerberos support.
-
-Sun Dec  1 16:20:21 1991  Jan-Simon Pendry  (jsp at achilles)
-
-	* (info_nis.c) changed so that it remembers if the NIS domainname
-	is set and doesn't repeatedly complain.  Message changed from an
-	Error to a Warning.
-
-	* (sfs_ops.c) added linkx fstype.  linkx is the same as link but
-	it also checks that the target exists.  This makes it useful for
-	wildcard map entries.
-
-	* (wire.c) applied changes from Dirk Grunwald.  Now stands a
-	better chance of correctly determining the network name.
-
-	* (map.c) changes in timeout_mp to cause second and subsequent
-	backgrounded unmount attempts to backoff and so reduce the chance
-	of running more than one backgrounded unmount at a time.
-
-	* (misc_rpc.c) bug fix from Martyn Johnson to avoid xdr_free'ing
-	the wrong piece of memory.  This was causing random core dumps,
-	often with a stack trace through pickup_rpc_reply.
-
-Sun Sep 15 21:16:38 1991  Jan-Simon Pendry  (jsp at achilles)
-
-	* Release 5.3 alpha 14.
-
-	* (os-osf1.h) merged in OSF/1 support.
-
-Sun Aug  4 18:25:04 1991  Jan-Simon Pendry  (jsp at achilles)
-
-	* (os-stellix.h) merged in Stellix support.
-
-	* (os-u4_2.h) merged in Ultrix 4.2 support.
-
-	* (host_ops.c) made TCP the default transport protocol.  Define
-	HOST_RPC_UDP somewhere to get UDP transport.
-
-	* (many) added support for ${remopts}.  Suggested by Steve
-	Heimlich.  remopts is the same as opts, but is used when the
-	remote server is not on the local network.  If it is not set it
-	defaults to whatever value ${opts} has.
-
-Tue May  7 22:30:00 1991  Jan-Simon Pendry  (jsp at achilles)
-
-	* Checkpoint for Berkeley network tape II.
-
-Sat May  4 22:06:24 1991  Jan-Simon Pendry  (jsp at achilles)
-
-	* New Berkeley Copyright.
-
-	* (mntfs.c) more short-circuiting in realloc_mntfs().
-
-	* (host_ops.c) increase RPC timeout to 20 seconds.
-
-	* (info_hes.c) now supports lookup in other domains.
-
-	* (srvr_nfs.c) call map_flush_srvr whenever a server comes up.
-
-	* (map.c) added hook to flush hung file servers.
-
-	* (wire.c) make loop step more portable.
-
-	* (util.c) fix for compiling on rios.
-
-Sun Apr 21 21:54:52 1991  Jan-Simon Pendry  (jsp at forest)
-
-	* (util.c) ignore EINVAL returned by rmdir().
-
-	* (am_ops.c, afs_ops.c) remove SunOS4 map compat code.
-
-	* (nfsx_ops.c) don't clear MFF_MOUNTING until finished mount attempts.
-
-	* (nfsx_ops.c) don't call sched_task more than once.
-
-	* (afs_ops.c) don't call afs_bgmount if a mount is in progress.
-
-	* (info_file.c) handle case where map ends with \
-
-Fri Apr  5 19:23:50 1991  Jan-Simon Pendry  (jsp at forest)
-
-	* Release 5.3 Alpha 12.
-
-	* (util.c) don't clear MFF_MOUNTING flag if mount is still in progress.
-
-	* (srvr_nfs.c) calls make_nfs_auth() as required.
-
-	* (host_ops.c) calls make_nfs_auth() as required.
-
-	* (afs_ops.c) allow foreground mounts to return pending.  This is
-	used by nfsx_ops.c.
-
-	* (mapc.c) uses new RE_HDR abstraction coping with systems which
-	already have the re package installed.
-
-	* (nfsx_ops.c) automatically generates a suitable sublink to make
-	things work.  Remounts now work correctly, but are done in the
-	foreground so there is a possibility that things may hang.  This is
-	too hard to do differently.
-
-Wed Apr  3 17:49:05 1991  Jan-Simon Pendry  (jsp at achilles)
-
-	* (nfs_ops.c) HAS_NFS_QUALIFIED_NAME is a new compile time switch
-	which puts a qualified domain name into the RPC authentication
-	instead of using the default value.  Abstracted this out into new
-	routine called make_nfs_auth().
-
-	* (afs_ops.c) fixed bug which caused spurious ENOENTs to appear.
-	this was caused by some code motion which also got slightly
-	altered int the process.  moral: don't make two changes at once.
-
-Sun Mar 17 12:05:27 1991  Jan-Simon Pendry  (jsp at forest)
-
-	* Release 5.3 Alpha 11.
-
-	* (amq.8) Updated.
-
-	* (amq.c) Added new -v option which displays the version number of
-	the target Amd.  Also added support to Amd and reworked newvers
-	script.  Got rid of rcs_info.c.
-
-	* (mk-amd-map.c) Changed name of remove function to avoid clash
-	with ANSI C.
-
-	* (wire.c) Fixed to work with new 4.4BSD sockaddr's.
-
-	* Changed const to const everywhere and added new define in config.h.
-
-	* (mk-amd-map.c) New -p option which just writes the output to
-	stdout.  Useful for making NIS or Hesiod maps.
-
-	* (amdref) Small updates and clarifications.
-
-Sat Mar 16 20:35:17 1991  Jan-Simon Pendry  (jsp at forest)
-
-	* (amq_subr.c) Flush request now flushes all internal caches.
-
-	* (amq_subr.c) Changed xdr_amq_mount_tree to return only the
-	required sub-tree.
-
-	* (ifs_ops.c) Added missing return 0; to ifs_mount.
-
-Sat Mar  9 19:31:25 1991  Jan-Simon Pendry  (jsp at forest)
-
-	* (get_args.c) Output the primary network interface information
-	with the -v option.
-
-	* (mapc.c) Fixed spurious warning about "root" map not supporting
-	cache mode "all".  Added new (unnamed) cache mode MAPC_ROOT.
-
-	* (info_nis.c) Fixed order number testing which was the cause of a
-	loop.
-
-Sun Mar  3 17:57:03 1991  Jan-Simon Pendry  (jsp at forest)
-
-	* Release 5.3 Alpha 10.
-
-	* Introduced new inet_dquad routine which prints IP addresses in
-	dotted quad format.  The C library routine is not used because it
-	uses a static buffer and it takes a structure argument on some
-	machines and unsigned longs on others.  This confuses the hell out
-	of some compilers and causes SEGVs.
-
-	* task_notify becomes do_task_notify to avoid clash with Mach.
-
-	* (mntfs.c) In realloc_mntfs, the private data field wasn't being
-	cleared out when the mntfs object was being re-used.  This meant
-	that the data might be used for the wrong mount, so causing
-	various obscure errors.
-
-	* (info_file.c) Reworked to provide support for map cache "sync"
-	option.
-
-	* (mapc.c) Added new "sync" option to map cache.  This ensures
-	that the cached data doesn't become stale wrt the source.
-	Currently this isn't implemented for passwd and hesiod maps.
-
-Wed Feb 27 11:38:07 1991  Jan-Simon Pendry  (jsp at forest)
-
-	* (afs_ops.c) Fixed pid put in fs_hostname for toplvl mount.
-
-Sun Feb 24 19:37:55 1991  Jan-Simon Pendry  (jsp at forest)
-
-	* (wire.c) New module which determines the name of the primary
-	attached network.  This could be used to determine which
-	server to use.
-
-	* (srvr_nfs.c) Changed mount daemon port mapping caching.  This is
-	now much more eager to recompute the mapping than before.  Will
-	also now work even if pinging is switched off (for example "tcp").
-
-	* (info_nis.c) Added back old NIS reload code to allow NIS maps to
-	support "regexp" caching.
-
-	* (mapc.c) Added support for "regexp" caching.  This is a type of
-	map cache where the entries are all REs to be matched against the
-	requested key.  This implies "all" since all the keys must be
-	loaded for the search to work.
-
-Sat Feb 23 15:32:43 1991  Jan-Simon Pendry  (jsp at forest)
-
-	* (afs_ops.c) Avoid spurious error messages about discarding a
-	retry mntfs.
-
-	* (amq_subr.c) Removed inet_ntoa call due to disagreement between
-	gcc and libc about 4 byte structure passing.
-
-	* (xutil.c) Changed way initial logging is done to make command
-	line more usable.  Default logging flags are set statically and
-	can then be modified by -x options.  At the end an additional call
-	to switch_option is made to initialise xlog_level_init.
-
-	* (umount_fs.c) ENOENT now treated the same as EINVAL.  If the
-	filesystem gets removed and the mountpoint deleted then just
-	assume the filesystem isn't there - which it isn't.
-
-	* (host_ops.c) Now copes with unmount failures by attempting to
-	remount the filesystems which had been unmounted.
-
-	* (host_ops.c) Added check during fhandle collection to detect
-	duplicate entries in the export list (from Stefan Petri).
-
-	* (nfsx_ops.c) Reworked to correctly keep track of what is and
-	isn't mounted.
-
-Sun Jan 27 16:58:02 1991  Jan-Simon Pendry  (jsp at achilles)
-
-	* (misc-next.h) Added missing NeXT config file.
-
-	* Merged Harris HCX/UX support from Chris Metcalf.
-
-	* (ifs_ops.c) added ifs_fmount entry point to keep nfsx_ops happy.
-
-Sun Jan 13 18:19:19 1991  Jan-Simon Pendry  (jsp at beauty)
-
-	* (nfsx_ops.c) play with opt_fs field to make sure it is unique.
-
-Fri Dec 21 15:35:45 1990  Jan-Simon Pendry  (jsp at forest)
-
-	* Release 5.3 Alpha 9.  This is still not Beta!
-
-	* (host_ops.c) use normalized hostname in mtab entries, from
-	Chris Metcalf.
-
-	* (map.c) enum ftype -> ftype, from Andrew Findlay.
-
-Mon Dec 17 01:11:25 1990  Jan-Simon Pendry  (jsp at beauty)
-
-	* (amdref.texinfo) merged in fsinfo documentation from Nick.
-
-Sat Dec 15 15:39:07 1990  Jan-Simon Pendry  (jsp at beauty)
-
-	* (clock.c) minor tweaks to messages.
-
-	* (sfs_ops.c) make the opt_fs field unique, rather than always
-	".", but make sure it still begins with a "." to avoid a clash
-	with any other existing mounts.
-
-	* (amd.c) changed way local IP address is obtained to avoid using
-	a call to the name server.  It was observed that if the power to
-	the building goes and everything reboots simultaneously then there
-	would be a good chance that the nameserver would not recover
-	before Amd on another machine required it.  This happened :-)  Now
-	use the RPC get_myaddress call.
-
-	* (info_hes.c) added hesiod_reload code from Bruce Cole.
-	Optionally compiled when HAS_HESIOD_RELOAD is defined.
-
-	* (amq_subr.c) fix "security" check.
-
-	* (amq.c) make sure a privileged port is allocated.  In fact
-	RPC3.9 and newer make this guarentee but older versions don't so
-	we do it here.
-
-Sun Dec  2 21:30:07 1990  Jan-Simon Pendry  (jsp at achilles)
-
-	* (afs_ops.c) fixed problem with pointer pre-increment.
-
-Mon Nov 19 00:31:28 1990  Jan-Simon Pendry  (jsp at achilles)
-
-	* (nfs_ops.c) saved filehandle with mntfs structure.  this allows
-	nfsx unmounts to be undone even if the filehandle cache has lost
-	the entry.  all of this is bogus and deserves a rewrite...
-
-Sun Nov 18 22:55:43 1990  Jan-Simon Pendry  (jsp at achilles)
-
-	* (nfsx_ops.c) now handles mounts of root filesystem correctly.
-
-	* (afs_ops.c) fixed dfs_ops definition to call toplvl_mounted when
-	done, so making sure that a map cache reference is set up.
-
-Sun Nov 11 21:09:34 1990  Jan-Simon Pendry  (jsp at achilles)
-
-	* (fsinfo/wr_fstab.c) has per-ostype fstab rules.
-
-	* (fsinfo/fsi_lex.l) now works correctly with flex.
-
-Mon Nov  5 00:08:30 1990  Jan-Simon Pendry  (jsp at achilles)
-
-	* Release 5.3 Alpha 8.  No more new features from now to 5.3Rel.
-	Call next one Beta.
-
-	* (amdref.texinfo) more updates.
-
-	* (info_union.c) reload routine now adds a wildcard pointing to
-	the last named directory so that new files get created correctly.
-
-Sun Nov  4 22:02:50 1990  Jan-Simon Pendry  (jsp at achilles)
-
-	* (os-u4_0.h) Ultrix 4.0 support merged.
-
-	* (os-utek.h) Utek 4.0 support merged.
-
-	* (amdref.texinfo) fixed & updated.
-
-	* (nfsx_ops.c) reworked string munging to prevent ..//.. strings
-	from occuring.
-
-	* (util.c) am_mounted now correctly updates the am_node for
-	duplicate mounts.
-
-	* (afs_ops.c) added union fstype.  derived from "toplvl" except it
-	causes all the filesystems to be mounted.  cannot be used for
-	filesystem types whose mounts may be defered (eg nfs) since it
-	doesn't retry the mounts.
-
-	* (info_union.c) map type for union fstype support.  currently
-	can't handle being given automounted filesystems - causes a
-	deadlock.
-
-Sun Oct 21 22:56:16 1990  Jan-Simon Pendry  (jsp at achilles)
-
-	* (fsinfo/*) finally integrated the fsinfo package.  currently no
-	documentation or man page.  this is a pre-req to getting mmd up.
-
-Sun Oct 14 20:02:11 1990  Jan-Simon Pendry  (jsp at achilles)
-
-	* (amdref.texinfo) reworking of documentation continues.
-
-	* (clock.c) reschedule_timeouts() now called in the event that the
-	system clock goes backwards.  this is possible during the average
-	bootstrap juggling act with timed/xntpd etc.  especially useful if
-	your machines TOY clock gets way ahead of time.
-
-Sat Oct  6 19:57:55 1990  Jan-Simon Pendry  (jsp at achilles)
-
-	* (map.c) when expanding the filehandle for a server which is
-	down, don't update the ttl on the original node unless a new node
-	gets allocated.  this should give the original mount a chance to
-	go away as soon as the server comes back.
-
-	* (arch, os-type) Updated.
-
-	* (nfs_ops.c) Added "noconn", "spongy" and "compress" mount
-	options for 4.4 BSD.
-
-Sun Sep 30 18:37:54 1990  Jan-Simon Pendry  (jsp at beauty)
-
-	* Release 5.3 Alpha 6.
-
-	* (util.c) domain_strip now doesn't leave partial domains behind.
-	if it can't strip the complete domain it leaves the string untouched.
-
-	* (restart.c) remember to initialise opt_opts field from mtab.
-
-	* (nfs_ops.c) supports "nocto" option for SunOS4.1.
-
-	* (os-irix.h) new SGI Iris port.
-
-	* (os-next.h) new NeXT port.
-
-	* (os-dgux.h) new DG/UX port.
-
-	* (many) fixed problem where mf_opts was being used for two
-	different purposes.  Now have two fields.
-
-	* (mapc.c) error map prints error message whenever used.
-
-	* (mapc.c) wildcard code rewritten.
-
-	* (util.c) slpit into two parts - some code now in xutil.c.  This
-	is used by mmd (not yet shipped).
-
-Sun Aug 19 19:58:16 1990  Jan-Simon Pendry  (jsp at achilles)
-
-	* (srvr_nfs.c) reduce verbosity of "nfs server yoyo is ok" messages.
-
-	* (opts.c) fix deslashification in expand.
-
-	* (nfs_start.c) amq registering done just before the server kicks
-	in.  running amd with nothing to do leaves the portmapper in peace.
-
-	* (mapc.c) bootstrap code abstracted to allow AMQ_MOUNT entry point.
-
-	* (nfsx_ops.c) new filesystem type, supporting groups of nfs
-	mounts.  needs abstracting to allow groups of (*) mounts.
-
-	* (am.h, *_ops.c) am_ops structure changed; corresponding changes
-	in the filesystem implemention source.  Change was to allow nfsx
-	filesystem implementation.
-
-	* (amd.c) hostname defaults to "localhost" startup code re-ordered
-	so that logging still works in case things go wrong early.
-
-	* (am_ops.c) new routine to print list of available fs types; used
-	by the -v option.
-
-	* (info_file.c) bug fix to make reloads work correctly.
-
-	* (mtab_file.c) does locking on single write, to avoid trashing
-	mount table when a mount and unmount are done at the same time.
-
-	* (mount_fs.c) automount hack removed since afs_ops no longer
-	needs it.
-
-	* (afs_ops.c) split "auto" into several other filesystem types.
-	Now much cleaner.
-
-	* (amq.c) new -M option.
-
-	* (amq_subr.c) support for AMQ_MOUNT added.
-
-	* (amq.x) new AMQ_MOUNT RPC call allows mount map entries to be
-	passed in at run-time.  Automount points can now be added
-	dynamically, but not yet deleted.
-
-Sat Jun 23 22:12:48 1990  Jan-Simon Pendry  (jsp at beauty)
-
-	* Release 5.2 for Berkeley.
-
-	* (*) Re-organised source code layout.  Now much more complicated.
-
-	* (map.c) code which flushed the kernel name cache is not really
-	needed now that the modify times on the automount directories are
-	correctly updated so ifdef the whole lot.  Remove later...
-
-	* (map.c) make sure that the automount directories modify times
-	are updated when a change occurs so that the nfs client code can
-	decide when to update its name cache.
-
-	* (srvr_nfs.c) fixed bug which caused mounted filesystems to
-	appear down when they were up.
-
-	* YP becomes NIS.
-
-Mon May 28 19:50:34 1990  Jan-Simon Pendry  (jsp at achilles)
-
-	* (amd.tex) substantially updated with more explanation of the
-	theory and more examples.
-
-	* (nfs_stubs.c) statfs now claims to have a single used block.
-	Avoids ambiguity between 100% and 0% full.
-
-	* (nfs_stubs.c) changed to allow the size of symlinks optionally
-	to be accurate wrt the length of the string returned.  Optional
-	because it is cheaper to ignore the length when doing a getattr
-	and just send any length for the readlink.  However, this breaks
-	on some systems (e.g. Ultrix).
-
-	* (mount_fs.c) automount points get marked type "nfs" instead of
-	"ignore".  This is to fix an interaction with getwd().  Can go
-	away when getwd() gets re-written.  Really only applies to SunOS4
-	but change applies to everything to keep consistent across platforms.
-
-	* (mount_fs.c) abstracted out mount options into a table and
-	corresponding loop.
-
-	* (srvr_nfs.c) make sure portmap information is available when
-	needed, not just after a ping has succeeded.  This needed changing
-	after the ping algorithm got changed.
-
-	* (mntfs.c) fixed incorrect reference to mf_error instead of mf_flags.
-
-	* (nfs_start.c) keep track of number of fds in use, so don't run
-	select on system maximum (which is bad news if you have a large
-	system maximum).
-
-	* (host_ops.c) new NFS tree mount filesystem type (ala Sun -hosts).
-
-	* (nfs_ops.c) abstracted out NFS mount code to support host_ops.
-
-	* (afs_ops.c) dfs_readlink now returns the am_node, instead of the
-	link.  This allows getattr to return the correct set of attributes
-	so keeping Ultrix happy.
-
-	* (afs_ops.c) Make certain the hostname field given to mount()
-	does not get too long - otherwise random EINVAL errors occur.
-
-	* Putting closing comments on all #endif's
-
-Sun May 13 16:07:21 1990  Jan-Simon Pendry  (jsp at achilles)
-
-	* (srvr_nfs.c) second rewrite of NFS ping algorithm.
-
-Sun Apr 29 21:12:33 1990  Jan-Simon Pendry  (jsp at achilles)
-
-	* (nfs_stubs.c) re-arranged readlink code to avoid need to
-	pre-mount a direct filesystem whenever possible.
-
-	* (host_ops.c) finally incorporated new module to support /net
-	mount point.
-
-Sat Mar 24 13:18:47 1990  Jan-Simon Pendry  (jsp at achilles)
-
-	* (nfs_stubs.c) workaround added to rename entry point to avoid
-	arguments with NFS client code.
-
-	* (srvr_nfs.c) changed the way NFS pings are done and cleaned up
-	the process for deciding when a server is up or down.  Now there
-	is just a simple time limit on a reply from the server.  The limit
-	is adjusted depending on whether the state of the server is known.
-
-	* (opts.c) fixed bug with ${var/} expansion et al.  Added ${varN}
-	N = 0..7 for use as scratch variables.
-
-	* (mntfs.c) fixed bug in dup_mntfs().
-
-Thu Jan 11 16:56:41 1990  Jan-Simon Pendry  (jsp at achilles)
-
-	* Release 5.1c.
-
-	* (amq*) has new options.  -f flushes the map cache and -m prints
-	information about mounted filesystem and fileservers.
-
-Tue Jan  2 14:44:21 1990  Jan-Simon Pendry  (jsp at achilles)
-
-	* (util.c) am_mounted() patches the path for "direct" mounted
-	filesystems - cosmetic.
-
-	* (afs_ops.c) when possible sets a small kernel attribute cache
-	timeout on the automount points.
-
-	* (nfs_stubs.c) delete() and rmdir() operations implemented.  Used
-	when a mount point is timed out so the kernel name cache gets to
-	know about the changes.  Fixes most ESTALE errors.
-
-	* (nfs_stubs.c) New do_readlink() function added.  This is used to
-	make sure that a filesystem is mounted at the time a link is read
-	in the case of "direct" mounts.  Done so that the length of the
-	link is available when the initial getattr is done on the mountpoint.
-
-	* (sfs_ops.c) Changed implementation to avoid race conditions.
-	The link target is re-arranged so that sublink points to the
-	target and fs always points at ".".
-
-	* Fixed mount flag bug on Ultrix.
-
-	* Added support from Sjoerd Mullender for Alliant FX/4 and Encore
-	Multimax.
-
-Thu Dec  7 17:55:29 1989  Jan-Simon Pendry  (jsp at achilles)
-
-	* (afs_ops.c) dfs_readlink now does a new_ttl on the node it
-	returns.
-
-	* (afs_ops.c) next_nonerror_node now implements the task after
-	which it is named.
-
-Tue Nov 28 17:20:52 1989  Jan-Simon Pendry  (jsp at achilles)
-
-	* Release 5.1b.
-
-	* (restart.c) Generates link nodes for any unrecognised filesystem
-	types and then marks them so that they are never deleted (since
-	they could never be automounted later).
-
-	* (os-*.h) Irrelevant #undef's deleted.
-
-	* (arch) Now knows about AIX on RTs.
-
-	* (amq.c) Rationalised the output.  Now only gives you what you
-	asked for.
-
-	* (am.h) New macro: FSRV_ISDOWN(fs), which checks whether a
-	fileserver is down.
-
-	* (afs_ops.c) When a mount fails due to a timeout the underlying
-	filesystem is ripped away and replaced with an error fs.  This
-	avoids the possibility of being left with a single error reference
-	to a valid mounted filesystem.
-
-Thu Nov 23 18:04:29 1989  Jan-Simon Pendry  (jsp at achilles)
-
-	* (nfs_start.c) Re-order bootstrap sequence to avoid potential
-	deadlock if restart() ends up accessing one of the automount points.
-
-	* (amq.c) Don't produce default mount output if one of the -l, -x
-	or -D options was used.
-
-	* (umount_fs.c) Add alternative unmount routine for 4.4 BSD.
-
-Mon Nov 20 16:22:50 1989  Jan-Simon Pendry  (jsp at achilles)
-
-	* (os-bsd44.h) Fixed redefinition of UMOUNT_FS.
-
-	* (info_ndbm.c) Added missing #include <sys/stat.h>.
-
-	* (mapc.c) Fixed typo in ifdef around gdbm config entry.
-
-Sat Nov 18 16:39:13 1989  Jan-Simon Pendry  (jsp at achilles)
-
-	* (util.c) If "/" is automounted, make sure it is never timed out.
-
-	* (mtab.c) Missing clock invalidation added in read_mtab (from a file).
-
-	* (mntfs.c) realloc_mntfs simplified.
-
-	* (map.c) Closed a race condition during shutdown when second and
-	subsequent duplicate mounts were deleted prematurely.
-
-	* (afs_ops.c) Duplicate mounts are now given the correct return
-	code.
-
-Fri Nov 17 18:58:18 1989  Jan-Simon Pendry  (jsp at achilles)
-
-	* 5.1 Release.
-
-Thu Nov 16 17:57:02 1989  Jan-Simon Pendry  (jsp at achilles)
-
-	* (mntfs.c) Make sure inherit mntfs structures are not cached
-	after last reference; otherwise a second reference to the
-	inherited filesystem will get stuck on the inherit rather than the
-	(now) fully mounted filesystem.
-
-	* (am.c, nfs_start.c) After forking the server, make sure the
-	parent does not exit until the automount points are mounted.  This
-	allows a clean sequence during system startup.
-
-	* Initial port to 4.4 BSD.  Several new configuration abstractions
-	were added to make this port possible.
-
-Thu Nov  9 21:42:14 1989  Jan-Simon Pendry  (jsp at achilles)
-
-	* (afs_ops.c, opts.c) Added map logging to facilitate mount map
-	debugging without needing a -DDEBUG version of Amd.
-
-	* (afs_ops.c) Make sure the length of the fs_hostname mount
-	parameter does not exceed MAXHOSTNAMESZ.
-
-Wed Nov  8 13:44:02 1989  Jan-Simon Pendry  (jsp at achilles)
-
-	* Change the message log format to indicate the severity of the
-	message to allow simpler analysis of the log file.
-
-Tue Nov  7 14:11:36 1989  Jan-Simon Pendry  (jsp at achilles)
-
-	* 5.0 Patchlevel 11.
-
-	* (os-bsd44.h) Initial guess at 4.4 BSD definitions.
-
-	* (os-aux.h) Port for Macintosh II from Julian Onions.
-
-	* (amq.c) Output formats cleaned up.  AMQ_MNTTREE is still broken
-	in amq_subr.c though.
-
-	* (afs_ops.c) If a mount timed out, for example an NFS server was
-	down at the time, it was possible for the error code to remain
-	unset thus jamming that mount node in a state from which it could
-	not recover.  Just make sure that the mf_error field gets filled
-	in when an error occurs.
-
-	* (afs_ops.c) strsplit is run over /defaults to avoid problems
-	with whitespace creeping in.
-
-Sun Nov  5 11:50:51 1989  Jan-Simon Pendry  (jsp at achilles)
-
-	* (util.c) am_mounted: Added missing initialisation of stats.s_mtime.
-
-Fri Nov  3 17:33:02 1989  Jan-Simon Pendry  (jsp at achilles)
-
-	* 5.0 Patchlevel 10.
-
-	* Changed the copyright.
-
-Thu Nov  2 17:07:53 1989  Jan-Simon Pendry  (jsp at achilles)
-
-	* 5.0 Patchlevel 9.
-
-	* (opts.c) new option syntax: == != :=
-
-	* (nfs_ops.c) Less caching of filehandles.  Now cached errors are
-	discarded after use.
-
-	* (mtab.c) now attempts to deal with a lack of open file slots (ENFILE).
-
-	* (mount_fs.c) automount entries in the mount table now have a
-	dev= entry in the same way as NFS and UFS.
-
-	* (mntfs.c) mntfs nodes are now cached after the last reference
-	and discarded <ALLOWED_MOUNT_TIME> seconds later.  This avoids
-	thrashing during a mount.
-
-	* (mapc.c) map default cache mode is now selected with
-	"mapdefault", not "default"
-
-	* (amd.tex) numerous clarifications.  Still more work required...
-
-	* (amq_subr.c) now allows the -x option of amq to operate.
-
-	* (afs_ops.c) afs_bgmount now keeps track of which filesystem
-	needed retrying and ensures that the mount node in the
-	continuation correctly points at an unmounted filesystem.  This
-	fixes a problem whereby a valid mounted filesystem could appear to
-	have failed to mount.
-
-	* Configure now gives more of a running commentary and checks
-	whether os-type and arch actually worked.
-
-	* Allow spurious ';'s in a mount location.
-
-Fri Oct 27 14:03:31 1989  Jan-Simon Pendry  (jsp at achilles)
-
-	* foo=blah changed to foo:=blah, foo==blah and foo!=blah.
-
-	* -l stderr changed to -l /dev/stderr.
-
-Thu Oct 19 15:34:28 1989  Jan-Simon Pendry  (jsp at achilles)
-
-	* 5.0 Patchlevel 6.
-
-	* LOG_INFO messages have been rationalised so that some
-	statistics, graphs and so on can be generated.
-
-	* Transaction ID's for RPC calls are now allocated by the
-	individual callers, rather than from a central pool.  This
-	decreases the load on mount daemons and NFS servers since the
-	same XID is used for retries when needed.
-
-	* Many fine details of the new data structures have been changed.
-	Some areas have been optimized.
-
-Fri Oct 13 12:31:26 1989  Jan-Simon Pendry  (jsp at achilles)
-
-	* Restart code re-implemented to work with the new data structures.
-
-	* Fine tuning applied to new NFS server modeling code.
-
-Thu Oct 12 15:57:24 1989  Jan-Simon Pendry  (jsp at achilles)
-
-	* Added ${/var} and ${var/} variable expansions.  The first gives
-	the "basename" component of the variable, the latter gives the
-	"dirname" component.  Additionally, spurious /'s are deleted after
-	the variable expansions is complete.
-
-	* Added new -C option to allow the machine's cluster name to be
-	given to amd.  ${cluster} fetches the value and can be used as
-	another selector.
-
-	* Broken the major data struct (am_node) into three layers:
-	am_node (one for each automount node), mntfs (one for each mounted
-	filesystem) and fserver (one for each file server).  Machine
-	up/down state is maintained in the fserver layer.  Filesystem
-	mount/unmount state is maintained in the mntfs layer.  This change
-	fixes the last known major problem caused by the lack of a central
-	focus for filesystem and fileserver status.  There is a dummy file
-	server layer for local filesystems (ufs, link, program, error).
-
-Tue Oct 10 11:15:42 1989  Jan-Simon Pendry  (jsp at achilles)
-
-	* 5.0 Patchlevel 5.
-
-	* (nfs_ops.c) the filehandle cache is now flushed when a
-	filesystem is unmounted.  This avoids ending up with stale
-	information if a server bounces.
-
-	* (clock.c) new module to implement callouts.  Many other
-	routines changed to use callouts instead of messing with ttl
-	fields.
-
-Sun Oct  1 17:08:20 1989  Jan-Simon Pendry  (jsp at achilles)
-
-	* 5.0 Patchlevel 3 & 4.
-
-	* Numerous cleanups.
-
-Wed Sep 13 14:30:05 1989  Jan-Simon Pendry  (jsp at achilles)
-
-	* 5.0 Patchlevel 2.
-
-	* (nfs_ops.c) portmap information is not remembered beyond the
-	basic filehandle cache interval.  That avoids problems when a new
-	portmap and/or rpc.mountd is started and the bound port changes.
-
-	* (mapc.c) cache reloads are automatically done every hour.
-
-	* Removed xlog macro in favour of plog() so that the log level
-	can be reflected through to syslog().  log() routine renamed to
-	plog() which takes an extra parameter indicating the log level.
-
-Tue Sep  5 20:00:19 1989  Jan-Simon Pendry  (jsp at achilles)
-
-	* (nfs_ops.c) when a server is known to be down, any cached file
-	handles and port mapping informaton is flushed since that may have
-	changed when it comes back up.
-
-	* (map.c) timeout no longer attempts to unmount a hung mount point.
-
-Mon Sep  4 14:49:18 1989  Jan-Simon Pendry  (jsp at achilles)
-
-	* (afs_ops.c) a mount node which timed out during mount is now
-	retained for the normal timeout interval rather than for a short
-	period.  This avoids wasting time retrying mounts from a server
-	which is down.
-
-	* (afs_ops.c) hung mounts are now detected and not used as a
-	duplicate mount - something which defeated the replacement fs
-	scheme.
-
-	* (nfs_ops.c) keepalive's now back-off when a server has gone
-	down.
-
-Thu Aug 31 21:18:35 1989  Jan-Simon Pendry  (jsp at achilles)
-
-	* 5.0 Patchlevel 1.
-
-	* Fixed several bugs which showed up in the keepalive
-	implementation when a gateway went down causing
-	a different sequence of errors than usual.
-
-Wed Aug 30 11:29:21 1989  Jan-Simon Pendry  (jsp at achilles)
-
-	* (amq.x) now uses a Sun assigned program number.
-
-	* Revision 5.0 - can now start using metaconfig.
-
-Tue Aug 29 14:36:48 1989  Jan-Simon Pendry  (jsp at achilles)
-
-	* (os-u3_0.h, os-type) now knows about DECstations (mips).
-
-	* (nfs_stubs.c) Added hooks to readlink entry point to call
-	per-fs readlink routine if it exists, otherwise old behaviour.
-
-	* (afs_ops.c) Added implementation of "type=direct".  This is
-	the same as "type=auto" but is itself the link to the
-	mount point, rather than being a directory containing a list
-	of links to mount points.
-
-Mon Aug 28 17:48:15 1989  Jan-Simon Pendry  (jsp at achilles)
-
-	* (afs_ops.c) Changed readdir to workaround a problem on
-	ultrix 3 where it seems to forget that eof has been reached.
-
-Thu Aug 24 15:17:55 1989  Jan-Simon Pendry  (jsp at achilles)
-
-	* Created "beta16".
-
-	* (afs_ops.c) /defaults is located along with every key.
-	this makes it possible to update the /defaults in
-	a map and get to use it.
-
-	* (mapc.c) added map cache synchronization support.  if
-	a file or ndbm map is updated the cache is junked so avoiding
-	things getting out of sync.
-
-Wed Aug 23 19:17:52 1989  Jan-Simon Pendry  (jsp at achilles)
-
-	* (os-u3_0.h) new file to support Ultrix 3.0
-
-	* (opts.c) allow environment variables to be accessed via
-	the same ${env} syntax used for options & selectors.
-
-Tue Aug 22 13:19:49 1989  Jan-Simon Pendry  (jsp at achilles)
-
-	* (opts.c, get_args.c) added support for kernel architecture
-	type to allow /usr/kvm to be automounted under SunOS 4.x.
-
-	* (os-xinu43.h) updated for june '89 release of MORE/bsd.
-
-	* (opts.c) fixed memory allocation problems where some strings
-	may not have been strdup'ed before they were free'ed so causing
-	the malloc arena to get into a twist.  This caused core dumps on
-	some machines and infinite loops on others.
-
-	* (*.c) clock handling is now done by a macro.  Global variable
-	clock_valid is > 0 (ie the time) when valid, 0 if invalid.
-
-	* (map.c) timeout code survived a complete rewrite and is now
-	O(n) rather than O(n^2).
-
-	* (info_hes.c) new database hooks for Hesiod nameserver.
-
-	* (get_args.c) the local sub-domain is picked up from the
-	hostname if it is not specifed with -d.  The subdomain is
-	then stripped from the hostname.
-
-	* (am.c) when a SIGTERM is received, an immediate abort
-	occurs - only the top-level automounts are unmounted; all
-	other mounts stay -- use amd -r to restart.
-
-	* (afs_ops.c) cleaned up key prefix handling.  Again updated
-	the "hostname" string passed to the kernel so that includes
-	the hostname, pid and mount point.
-
-Tue Aug  8 16:05:23 1989  Jan-Simon Pendry  (jsp at achilles)
-
-	* (nfs_ops.c) changed the way the file handle cache is managed.
-	No longer gets a race condition between something entering the
-	cache and being used and discard.
-
-Tue Jul 25 20:40:51 1989  Jan-Simon Pendry  (jsp at achilles)
-
-	* (map.c) changed fh_to_mp2 so that it does not return
-	ESTALE during shutdown.  it returns ENOENT instead which
-	avoids thrashing with the kernel.
-
-Sun Jul 23 15:06:10 1989  Jan-Simon Pendry  (jsp at achilles)
-
-	* (afs_ops.c) make sure the incoming key from the kernel
-	does not contain any characters which could cause trouble
-	during macro expansion (such as `"! etc).
-
-	* (afs_ops.c) fixed contruction of "mtab" entry.
-
-Fri Jul 21 11:01:05 1989  Jan-Simon Pendry  (jsp at achilles)
-
-	* (afs_ops.c) some changes to support the new startup
-	shutdown scheme.
-
-	* (map.c) startup and shutdown are now done using the
-	standard interfaces.  Startup is done by creating a
-	private cache map  ";root;" and then doing lookups
-	on all the names in it.  Shutdown is done by forcibly
-	timing out all the mount points including the automount
-	points.
-
-	* (info_*.c) modified to provide interface required by
-	mapc.c module.
-
-	* (mapc.c) new module to implement map caching.  Caching
-	can be controlled by an fs option.  "all" means cache
-	the entire map (if possible).  "inc" means cache things
-	incrementally.  "none" means never cache things.  Each
-	map type has a default caching mode which is used if
-	cache option "default" is used.
-
-Wed Jul 19 16:14:52 1989  Jan-Simon Pendry  (jsp at achilles)
-
-	* (sched.c) implements a general sleep/wakeup scheme and uses
-	it for sub-process handling.
-
-	* (nfs_start.c) task_notify() called from where it used to
-	be called.
-
-	* (nfs_ops.c) now implements a non-blocking rpc library.
-	Everything in nfs_ops was changed to use it.  This should
-	not be in this file and will be moved later.
-
-	* (map.c) if a mount point times out and it is deferred then
-	issue a wakeup so that it can be retried.
-
-	* (map.c) when creating a new mount point fetches the entry
-	"/defaults" from the associated map if no other options are
-	specified.
-
-	* (am.c) implements the -p (print process id) option.
-
-	* (afs_ops.c) a mount attempt now has a time-to-live of twenty
-	seconds.  if only deferred attempts are waiting after that
-	interval the kernel gets sent ETIMEDOUT.
-
-	* (afs_ops.c) the name by which the kernel knows the filesystem
-	has changed from pid%d@host to /mountpoint@host.  That looks
-	better to users who get hit by it.
-
-Fri Jul 14 18:46:16 1989  Jan-Simon Pendry  (jsp at achilles)
-
-	* (afs_ops.c) now knows about defered mounts - mounts which
-	are not in progress, not completed, and not failed.
-
-	* (sched.c) added new entry point sched_ast().  This simulates
-	a completed job.  The basic idea is to let something else return
-	to the main scheduling loop with a guarentee that it will be
-	called back when some other action has taken place.
-
-	* (nfs_ops.c) implemented a file handle cache.  The nfs_init
-	routine starts up a request for the filehandle and the mount
-	routine uses it when it arrives.
-
-Thu Jul 13 18:07:58 1989  Jan-Simon Pendry  (jsp at achilles)
-
-	* (afs_ops.c) found a race condition between an error occuring
-	and the am_node being timed out.  Fixed by updating the
-	time-to-live and keepalive counters in the node whenever
-	AMF_MOUNTING is cleared.  Also changed afs_lookuppn() so that
-	it doesn't destroy the node when it returns the error code.
-	This stops thrashing and the node is eventually timed out.
-	Now the only way a node gets deleted is by the timeout code
-	which seems more elegant.
-
-Tue Jul 11 15:36:44 1989  Jan-Simon Pendry  (jsp at achilles)
-
-	* Created "beta15".
-
-	* Fixed *all* references to "u2.2".  Some where missed in
-	the original change.  They are now u2_2.
-
-	* (mk-amd-map.c) new command.  Converts plain files into
-	ndbm databases for use by the info_ndbm module.  Hooks
-	included for future support for gdbm just as soon as I
-	can get a copy.
-
-Sun Jul  9 19:00:22 1989  Jan-Simon Pendry  (jsp at achilles)
-
-	* Created "beta14".
-
-	* (get_info.c) code to handle yp and files now split into
-	new files info_yp.c and info_file.c  New support for ndbm
-	databases is in info_ndbm.c.  A table in get_info.c controls
-	what and in which order things are searched.
-
-	* (map.c, nfs_stubs.c) better handling for hung mount points.
-	if a filehandle is passed in by the kernel which references
-	a hung node, then try to find a replacement, possibly by calling
-	lookup explicitly.
-
-	* (*.c) use new xlog(level)(message) interface
-
-Thu Jun  8 20:28:55 1989  Jan-Simon Pendry  (jsp at achilles)
-
-	* (nfs_ops.c, ufs_ops.c) when compiled with DEBUG, display
-	the fs options being used.
-
-	* (am.c) make test for root a little more polite.
-
-	* (get_args.c) update Usage message to include -r option.
-
-Wed Jun  7 16:28:51 1989  Jan-Simon Pendry  (jsp at achilles)
-
-	* (rpc_fwd.c) fwd_reply: if the recvfrom call fails because it
-	is interrupted then try again.
-
-Tue Jun  6 16:39:15 1989  Jan-Simon Pendry  (jsp at achilles)
-
-	* Created "beta12".
-
-	* (afs_ops.c) inheriting mount option list from command line
-	is now cumulative.  A -foo on the command line is prepended
-	to the default option list taken from the map.  This can be
-	used to override the ``default default'' options in opts.c.
-
-	* (get_args.c, am.c) added new -r (restart) option.  Restart of
-	mounted filesystems is only done if this option is specified.
-	[Should *not* be specified in /etc/rc.local of course. - wrong]
-
-	* (yp_master.c) make the enumeration error message more verbose
-	when debugging is enabled.
-
-	* (rpc_fwd.c) rearranged some declarations at the top.  Removed
-	a spurious call to free which was causing grief on some systems,
-	but not on Sun's.  [This problem was the reason for implementing
-	the -D mem option.]
-
-	* (opts.c) make sure opt_key and opt_path are set to a zero
-	length string unless otherwise specified.  Previously they
-	were a source of dangling pointers.
-
-	* (nfs_ops.c) make sure that the allocated nfs_private identifiers
-	are unique even when some filesystem are being restarted.  This mean
-	starting the basic allocation from 1, not zero.
-
-	* (am.h, get_args.c, util.c) added definition and implmentation of
-	a simple memory allocation trace (D_MEM).
-
-	* (afs_ops.c) afs_lookuppn: tightened up memory allocation and
-	delay string copying until last possible moment.
-
-Mon Jun  5 18:01:18 1989  Jan-Simon Pendry  (jsp at achilles)
-
-	* (Makefile.com) diffs: added new rule to generate diffs
-	between versions.
-
-	* (get_info.c) search_file: added a new dlog() to note when
-	wildcards are returned.
-
-	* (afs_ops.c) afs_lookuppn: call to init_map specifies efs as
-	the default ops structure.  If the location list only contained
-	defaults and no real mounts then this previously caused a null
-	pointer dereference.
-
-	* (map.c) last_used_map: Added new variable.  Keeps track of the
-	last used map, which may be wildly different from first_free_map.
-	This fixes bugs in several routines in this file.
-
-	* (util.c) mkdirs, rmdirs: Changed directory make/unmake.  It is
-	not possible to quickly determine how many directories need to
-	be created or deleted, so we try to make as many as possible.
-
-	* (opts.c) Added default values for rfs, rhost and fs.
-	The new defaults guarentee unique names to allow the NFS
-	keepalive stuff to work.
-
-Sun Jun  4 16:12:15 1989  Jan-Simon Pendry  (jsp at achilles)
-
-	* First draft of documentation included in the next release.
-
-	* Hooks for TFS added, though this still requires a lot of work.
-
-	* Re-implemented option handling.  Options are now allocated
-	dynamically on a per-mount basis in the continuation structure.
-
-	* Changed os type u2.2 to u2_2 to allow for regular expression
-	matching in selectors.
-
-	* Format of mount maps is now entirely different.  Instead of
-	guessing which filesystem type is being used, it is now explicitly
-	stated along with the required options.  Variable expansion is
-	done on the options and selectors are also implemented.  The
-	requested name can also contain any of the selectors.
-
-Wed May 24 15:21:39 1989  Jan-Simon Pendry  (jsp at achilles)
-
-	* Re-implemented NFS ping algorithm to use the new RPC forwarding
-	system.  This allowed a large amount of nfs_ops specific code
-	to be removed from nfs_start.c and moved to nfs_ops.c.
-	There is still no strategy for hung file systems.  At the moment
-	it will merely try to mount an alternative (or the same again)
-	to the same place in the file system.
-
-	* Added RPC forwarding package.  This supports general RPC gatewaying
-	over a UDP transport.  The idea is to put a packet identifier into
-	each outgoing RPC packet and then match that up in a database when
-	a reply comes in.  The database records the original packet identifier
-	(so that it can be replaced), the source address for the packet and
-	a function to call to do the forwarding.
-
-	* ChangeLog added between beta8 and beta9.  Should have done this sooner.
