11 # This needs to be run at the earliest possible point in the boot
14 # Based on the udev init.d script
16 # Thanks go out to the Gentoo developers for proving
17 # that this is possible to do.
19 # Yes, it's very verbose, feel free to turn off all of the echo calls,
20 # they were there to make me feel better that everything was working
21 # properly during development...
23 # don't use udev if sysfs is not mounted.
