How (if at all) does this cope with gdm multi-seat? Even if it isn't
possible for the same "real user" to be on more than one seat
simultaneously, if I understand it correctly, I think a multi-seat gdm
setup still wants to be running the greeter (as a system user, e.g.
Debian-gdm on Debian) on each seat.
(One possibility is to have some way for gdm to synthesize new uids, but
that needs OS-integrator-level support, e.g. a reserved uid range;
another is for each seat's greeter to set the necessary pile of extra
environment variables to avoid using the XDG_RUNTIME_DIR much, or at all.)
