Err, no, /proc/devices isn't a filesystem, it's a FILE. The idea being it's a list of major,minor's that are in the system, or perhaps something like: +8,0 +8,1 +8,2 +8,4 -8,1 +8,3 Where a proggie can then read the file and determine what is currently in the system, and by watching the file can see what devices are added/removed. NOTE: This is just a random thought on the layout, it prolly has lots of problems so don't think I'm suggesting it as a permanent solution. At least, this is my understand of the current thoughts going around on this...
