Let's see, on a recent kernel and recent udev I have as directories under /dev:
- disk, a pure udev creation, so no conflict there - loop, devices names under that are numeric. mount has /dev/loop%d and /dev/loop/%d hardcoded - bus/usb, this one collides with itself if flattened - snd/sound, names except for seq and timer are pretty much line noise. "timer" is scary though. - net with tun and (I think) tap. - pktcdvd with "control", not sure what tool uses it - misc is ok (they're all ex-/dev/xx devices) - video1394, dv1394, i2c with '0' as device name - dri with card%d - cpu which self-collides too - input with a potentially dangerous event%d
So, well, I think you're going to need directories for usb and cpu without doubt, and some of the rest is potentially risky, long-term wise.
OG.
