Given that subdirectories in /dev are not supported, and may be

This is probably the approach we will end up taking... just have to
actually do it :)
Oi! That's my code you'd be ripping out! ;o)
The reason for the subdirectories in the first place was to allow
LUNs to be identified by the port and node WWNs on the host and
RAID controller that uniquely described their path on the fibre
channel network. The WWNs are too long to include in the one
devfs node name, so the only option is to use a hierarchy.
Subdirectories do not remove the node name length limit.
Terry,
I just got a chance to try devfs_make_node() again on Leopard and it
still allows long path hierarchies just as it used to:
$ find /dev/Curiosity -name Leopard -exec ls -l {} \;
cr--r----- 1 root operator 17, 0 Dec 20 12:30 /dev/Curiosity/
got/the/better/of/me/so/I/dusted/off/some/old/code/to/try/a/deep/dev/
hierarchy/on/Leopard
