Bug#960287: cups forces the load of unneccessary modules which lets systemd-modules-load fail

[Some Anon <anon@anon.co>]

Package: cups
Version: 2.2.10-6+deb10u3
Severity: normal

Dear Maintainer,

since the recent update, cups causes the systemd-modules-load service to
fail, because it requires some modules in
/etc/modules-load.d/cups-filters.conf to be loaded, even though they are
not present on my system.

This then leads to a tainted state of the system according to systemctl,
which I'd consider to be a problem. 

The kernel modules in question are lp, ppdev, and parport-pc, which are
not necessary on my setup. Of course, my kernel is heavily customized to
fit my needs, but I still think, that cups should force modules to be
loaded even if they're neither needed on many setups, nor present on the
system.

For me, that bug was fixed by commenting the modules out in the file.
