Warning: I'm no expert on any of this -- but -- I'm listening to sound
right now using 2.5.69 (with devfs) and this is what I see:
There are NO symlinks from /dev to /proc. None.
/dev/snd and /dev/sound are real directories -- neither is a symlink.
#ls -l /dev/snd

Seems to me that any symlinks to /proc don't really belong in /dev.
Any opinions to the contrary? (Remember: my sound is working just fine.)
