I know devfs hasn't been maintained for a long time but the documentation for it comes with kernel source and there it is in menuconfig. Every time I hear that udev and sysfs replace devfs I wonder where to pick up the thread, where is that doc, where is the menuconfig option ;-) I guess there is a website but to bring people out of devfs with their /etc/devfs/compat_symlinks necessary to boot so they will have to manually make edits, it would be necessary to research the manual edits it takes to boot (md0 vs. md/0, tty vs. vc, etc., /etc/inittab, maybe etc pam or security ). If transitioning from devfs to udev sysfs comes down to one mistake so I can't boot and have to lilo append="rw init=/bin/bash" and edit /etc/innitab then I need the doc on boot partition to make the last edits to transition completely and save myself (not docs on a website). Shouldn't udev sysfs doc come with kernel source(maybe it does!?)? -Bob
