Ok, adding the Should-Start: udev line did not help. But I discovered that mountdevsubfs.sh is calling a program called "domount" which is not on my computer.
Line 32: domount tmpfs shmfs /dev/shm $SHM_OPT
Line 37: domount devpts "" /dev/pts -ogid=$TTYGRP,mode=$TTYMODE
Surely this should be replaced with something else?
