In F12 as distributed, anacron is started once an hour by crond,
and the /etc/cron.{daily,weekly,monthly} jobs are run _only_ by
anacron. See /etc/cron.d/0hourly and /etc/cron.hourly/0anacron .
Reasons for the change from earlier releases:
A) Avoid having many machines on a network all hammering a server
at the same time for daily, weekly, or monthly jobs. (Anacron
has provision for a random delay.)
B) Avoid having 2 different ways of starting the same job (sometimes
by crond, sometimes by anacron).
