systemd-repart /etc automount via discoverable partition specification

[Nils Kattenbeck <nilskemail@xxxxxxxxx>]

Hello, I am currently trying to build a linux image with discoverable
partitions in an A/B+etc+var scheme. I know that /usr and /var have a
corresponding partition UUID for automatically mounting them as per
DPS. However, I am not sure how to mount the /etc partition? Do I have
to specify it as the root partition and exclude /usr and /var in it?
Any help would be appreciated.

Kind regards, Nils
