Documentation: rootwait does not work if root=devicenumber
This makes it a bit tricky to use with LILO: Typing "root=/dev/... rootwait"
directly on LILO's prompt boots fine, but putting
root = /dev/...
append = "rootwait"
in lilo.conf fails, "rootwait" is silently ignored.

Cost me 4 hours of my life. If anyone feels up to fixing it init/do_mounts.c
instead of just documenting it, feel free. :-)
Cheers,
Jens
