Hmm, is this on a kernel without devtmpfs? Devtmpfs is expected to be
used with mdev (and we automatically enable it if you build a kernel
with BR).

So you don't have /proc and /sys? Is this also a custom rootfs skeleton
/ inittab? With the default one we do a mount -a before running /etc/init.d/rcS.
