I'm not sure what detail you intend here. One line per installworld
or similar sounds OK. One line per file seems excessive - especially
if you intend to retain history ("df -ki" suggests that a base install
is around 30,000 files).

How do you envisage this tool determining that /usr/sbin/foo is at
8.3-RELEASE-p2 and this is incorrect when userland is at (eg)
8.3-RELEASE-p4? Note that updating your system from 8.3-RELEASE-p2 to
8.3-RELEASE-p4 may not change /usr/sbin/foo and therefore it will
remain untouched.

SSH includes provision for displaying information prior to login - see
the "Banner" option in sshd_config. Note that this is most definitely
the wrong place to include system version details.
