If /var is a relative symlink to say mnt/var, it seems to work fine.
If /var is an absolute symlink to /mnt/var, rtkit-daemon fails to start
(complaining about /var/run/dbus/system_bus_socket not being available).
Tested with 232-18.

That all said, I'm not sure if supporting such a setup is actually worth it.
If you need to move /var to a separate location, ideally you make it a
separate mount point. If that is not possible, I would suggest you bind
mount the directory. This works fine.

Felipe, do you think this is worth investigating and spending time on?
