There is no need to have them as systemd correctly handles reloading
depending on the transaction ordering (even if systemd is installed
_after_ the package that installs the unit file).
Additionally, this also makes the scriptlets that manually invoke
systemctl conditional on systemctl being present, similar to what
systemd rpm macros do.
/var/lib/mock contains copy of OS. It is inteded for building packages. It usually contains duplicates to what you are looking for.

just BuildRequires: systemd is not enough, requirements are also
needed for the scriptlets. %systemd_requires exists to make this
easy, so let's use it.
"Crontab files must have mode 0600 or less permissive, and files in cron script
directories must have mode 0700 or less permissive."
Resolves: #1179721
Notably, the cron script (previously not %config) was renamed;
because it was not %config before, we should have liberty to change it
or move it around yet.
- Explicitly exclude fuse.sshfs. Ideally we'd like to exclude all fuse.* file
systems, sshfs is urgent because it it can hang updatedb.
Resolves: #604145, #608094
