In Solaris, IIRC, the devfs is actually /devices, and /dev/... are
symlinks to /devices/...  I seem to recall that the /devices nodes
have strict permissions, and the /dev symlinks have permissions that
override the permissions of the target ... or something.

It's been a while since I had to deal with this :-)
