[PATCH 0/1] fix on-first-boot for systemd >= 247

[Felix Moessbauer <felix.moessbauer@siemens.com>]

This patch should fix the missing machine-id, as well as the first-boot target.
Please review carefully and test this on various layers.
Feedback is highly appreciated, especially for more complex images like SWU, ro root+overlay, no initrd, ubuntu and debian buster.
