Hello Everybody,

I pinned *systemd* packages into Pin-Priority: -1, and re-compiled cron
package without anything related to systemd. But there is still
/lib/systemd/system/cron.service file as we can see below.

anto@d945gclf:~/packages/cron-3.0pl1-devuan$ grep -R systemd *
debian/changelog: * Remove any systemd related components
debian/changelog: * Change systemd definition in order for the daemon
to read an honor
debian/changelog: * Add systemd service file. Thanks to Michael

Which package actually generates all of the files and directories under
/lib/systemd and /etc/systemd if not the packages themselves, like cron
on the example above?

Thanks in advance.
