Thinking about this again, while implementing - if we need to customize
the unit file, do we want to:

- create an `override.conf` file in
  `/etc/systemd/system/proxmox-first-boot.service.d/`, like systemd
  would do it when using `systemctl edit <service>`?
  Disadvantage is, that that file isn't removed when removing the
  `proxmox-first-boot` package from the system (although we could do it
  via postrm maybe?)

- edit the unit file directly? That would mean that e.g. `debsums -c`
  would complain.

- even bother with a separate package and instead just write the unit
  file directly to /etc/systemd/system?
  Disadvantage here is that it would be a "lost" file, not managed by
  dpkg, and administrators would have to remove the file directly, if
  they want/need to.

I have implemented the first variant for now, for testing. But not sure
if it's the best way to go.
