[pve-devel] [RFC PATCH installer 2/5] fix #5579: first-boot: add initial service packaging

[Christoph Heiss]

While there is the `systemd-first-boot.service`, it uses the
non-existence of `/etc/machine-id` as condition to run. As we already
set up that file in the installer ourselves, we cannot use that.

Instead our service depends on a custom flag file in
/var/lib/proxmox-first-boot and will only run if that is present.
