| | | | | | | | | possible. Annotate <sys/param.h> lines with their current reasons. Switch to PATH_MAX, NGROUPS_MAX, HOST_NAME_MAX+1, LOGIN_NAME_MAX, etc. Change MIN() and MAX() to local definitions of MINIMUM() and MAXIMUM() where sensible to avoid pulling in the pollution. These are the files confirmed through binary verification. ok guenther, millert, doug (helped with the verification protocol)

with the same configuration to be run on the same net and they will keep their lease files/state in synch, and therefore allowing you to run redundant dhcpd's. Synchronization code stolen from spamd, uses an hmac key in /var/db/dhcpd.key if it exists. ok krw@ deraadt@
