Turn the ptrace(2) syscall into a kernel compile option, option PTRACE in
your kernel configuration file.
By default, GENERIC will enable this.
When PTRACE is not enabled, several ptrace-like features of the procfs
filesystem will be disabled as well (namely, the ability to read and write
any process' registers, as well as attching, single stepping and detaching
to/from processes).
This should help paranoid people build better sandboxens, and us to build
smaller ramdisks.
