/var/run/dbus/system_bus_socket is the canonical interoperable path,
hard-coded in quite a few places, and consistently available between
distributions. /run would have been better, but didn't exist when D-Bus
was introduced.

AIUI, neither systemd nor Debian support setups where /var/run and /run
are not synonymous, either via a symlink or a bind-mount.

I think making the systemd unit listen in /run would be OK, but perhaps
it would be good for systemd's debian-fixup.service to ensure that
/var/run == /run and (complain loudly | fix it with a bind-mount) if it
isn't?
