Jerry,

Once you disable "Automatically mount devfs at kernel boot", you need to
enter the command 'rc-update add devfsd' to add the appropriate symlink to
your /etc/rc.d/rc0.d directory.  This will cause Gentoo to enable devfs at
the appropriate time during bootup.

Note that the generated devfs system you get will be partially dependant
on kernel modules that you have loaded.  For example, I have sound modules
loaded and the /dev/sound/* entries retain their permissions properly from
boot to boot.
