Definitely. Plan 9 solution for devices is a bit awkward - the whole
#<character> notation looks like a kludge, but idea that you don't want
the whole /dev for everyone is _really_ sound. Example: for chroot jail
you want /dev/zero and possibly /dev/random, etc., but you don't want
/dev/hda there. Granularity should be better than all or nothing.
