Some packages within the same transaction (e.g. during system-upgrades) may
rely on having the pre-allocated system users and/or system groups provided
by the setup package already to be present when the dependee package gets
installed; waiting for the %%transfiletriggerin to run `systemd-sysusers`
will be too late in such cases.
The above statement also applies for the temporary files from this package
to be created by running `systemd-tmpfiles`.
