This is a systemd generator that provides cron daemon & anacron functionality
It dynamicaly translates /etc/crontab, /etc/cron.{d|hourly|daily|weekly|monthly|yearly}/* and user cronjobs into systemd .timer & .service units.
PTS: https://tracker.debian.org/pkg/systemd-cron
On Debian, systemd-cron is built in a way to ignore these legacy NO-OP jobs if the new equivalent .timer is present:

/etc/cron.d/debian-edu-config |
/lib/systemd/debian-edu-update-netblock.timer |
|
/etc/cron.d/mythtv-status |

/etc/cron.SCHEDULE/dpkg |
/lib/systemd/dpkg-db-backup.timer |
|
/etc/cron.SCHEDULE/lighttpd |
/lib/systemd/lighttpd-maint.timer |
|
/etc/cron.SCHEDULE/mythtv-status |
/lib/systemd/mythtv-status_health-check.timer |
|
/etc/cron.SCHEDULE/plocate |
/lib/systemd/plocate-updatedb.timer |
|
/etc/cron.SCHEDULE/privoxy |
/lib/systemd/privoxy-cleanup.timer |
|
/etc/cron.SCHEDULE/spamassassin |
/lib/systemd/spamassassin-maintenance.timer |
|
/etc/cron.SCHEDULE/sysstat |
/lib/systemd/sysstat-summary.timer |
|
This config is only needed if there is not a perfect 1:1 mapping between the job name and the timer name.
cron-daemon-common
systemd-cron depends on & obey to cron-daemon-common for some settings, like the default hour on which the @daily/@weekly/@monthly are run.
