Systemd 250 has been released. To say that the list of new features is
long would be a severe understatement; the developers have clearly been
busy.

systemd-homed now makes use of UID mapped mounts for the home areas.
If the kernel and used file system support it, files are now
internally owned by the “nobody” user (i.e. the user typically used
for indicating “this ownership is not mapped”), and dynamically
mapped to the UID used locally on the system via the UID mapping
mount logic of recent kernels. This makes migrating home areas
between different systems cheaper because recursively chown()ing file
system trees is no longer necessary.

(See this article for a description of
ID-mapped mounts).
