If they aren't a lingering user, they'll get a new systemd instance if 
they completely log out and back in again.

Alternatively, they can restart the running instance with:

   systemctl --user daemon-reexec

This serializes state across the re-execution, so services running in the 
instance are not killed.

There's few reasons a user might want to do this however. The only one I 
can think of is where the admin had updated the systemd package and the 
user wanted to make use of it immediately.
