Devtmpfs (which is used by devtmpfs/mdev/udev options) doesn't get automounted by the kernel when an initramfs is used, causing boot failures when a dynamic /dev is used. Fix it by adding a pre-init script to mount devtmpfs before running init. Reported-by: Arnout Vandecappelle <arnout@mind.be> Signed-off-by: Peter Korsgaard <jacmet@sunsite.dk>
