FWIW I am not sure that this is the right solution.  Logind has some
other interfaces (notably the /run/systemd file system and the cgroups)
and it really wants to be running from beginning to end.  If it's
bus-activated, could it be killed at some point if it's inactive?  If so
that would be bad I think.

Maybe it's OK.  It certainly solves the race, in some way.  I think
before a "guix system reconfigure" would restart logind, also; is that
still the case?  Which is better?  Very murky to me.
