Long ago, there was just /etc/daily. Then /etc/security was split out
of /etc/daily. Some time later, /etc/daily became a set of periodic(8)
scripts. Now, this evolution continues, and /etc/security has been
broken into periodic(8) scripts to make local customization easier and
more maintainable.

Copy /etc/cron.d to /etc/periodic per-request of many.
This wasn't done with a repository copy because there was no
history of any consequence. Flames to me.
