This fixes an issue that comes up every time a LXA TAC is freshly deployed with a new eMMC image via fastboot (e.g. not via RAUC update).
On the first boot after deploying an image the partition that should be mounted to /srv is not yet generated by systemd-repart.
systemd-repart does however run later in the boot process than systemd-gpt-auto-generator.
As a consequence of that there is no srv.mount on first boot and every unit that writes to /srv just clutters the rootfs with directories and files. This will result in issues on every subsequent boot as systemd-gpt-auto-generator does not generate mount units for directories that are not empty.
Currently we have to manually clear the cluttered /srv/ after flashing a new image. This is not acceptable.
Instead use the system-update.target to perform just the repartioning on first boot and make sure no units that clutter /srv are pulled in by system-update.target (e.g. via sysinit.target).
This PR supersedes #24 which tried to solve the same issue in a less fancy way. That PR can thus be closed.
