It's interesting to see something like this appear again. I certainly
agree (along with most people) that a standard should be defined.

I've also looked at this from originally the devfs angle. Maybe I should
pick it up again??. The idea was to have three directory tree's /dev,
/proc, /system. /dev contains the files for accesing the devices in a
Unix-like way. /proc for detailing only process information, and /system
for presenting control/information files.

So a possible structure could be :-

/dev/hda /dev/ide0/[ab][1-16]???
/system/modules/ide/.... <module specific stuff>

This is of course only a small bit. There's a alot of other things to
account for, like a name cache for perm's and onership of non-loaded
modules under the control of kerneld. However, it should give you an
idea of what it should look like.

If you are interested, I'll get back to it, and back to looking at
kernel code.
