What did /proc/mounts say? Is devfs really mounted on /dev, or did some
misplaced command create those files accidentally?
If you really have mount at boot enabled for devfs (and you don't override it
on the kernel boot line), you shouldn't need to mount it yourself at all (and
the script should be trying to, either). Are you using a initrd image by any
chance?
Are you absolutely positive you're running the version of the kernel that has
devfs enabled? Did you "make mrproper" before compiling (just a safety
measure)?
http://bugs.gentoo.org/ may be more appropriate for your problem unless you've
already tried it.
