include anacron as a subpackage. Each hour cron executes scripts from
cron.hourly which contains 0anacron executable.
0anacron script checks whether the regular jobs - cron.daily, cron.weekly
and cron.monthly
- were executed or not. The list of all regular jobs is in
/etc/regular-jobs instead of /etc/crontab. Manual pages mentioned
options how to set up regularly-jobs to behave the same way as in the
previous versions of cron.
