Lennart Poettering on Nostr: …context of DynamicUser=1: they allow such services to have persistent directories ...
…context of DynamicUser=1: they allow such services to have persistent directories on disk, that are properly owned by the short-lived UID. Implementing this comes with some ugliness however: what happens if I reference some state directory from a DynamicUser=1 service today where it will get UID X assigned, and tomorrow when I start it again it will get UID Y assigned?
Our solution was pragmatic: when this happens we recursively re-chown() the referenced directories…
