I do not mind if `pgrep' and `pkill' are moved to /bin. Note
that these were added to /usr because that's where they exist
on NetBSD, OpenBSD, Solaris and Linux. So we're not just
talking about hardcoded-paths in a few scripts that FreeBSD
users might have written for use only on FreeBSD. So, I expect
we will want symlinks to remain in /usr, forever, if we move
the programs to /bin.
(Moving them does seem reasonable to me. I'm just saying why
they were put in /usr in the first place...)
