Hi John,

you have root mounted read-only, and devfs enabled. I think you get into
trouble because of devfs. Without the devices you can't get the console
and thus you can't do anything with the computer. Furtheron init will
try to create the .initctl pipe in /dev, which is due to the not mounted
devfs in a directory of the READ-ONLY root.

My guess: Your flesystem is readable and (mostly) correct. As some
others before me mentioned -- we don't know what you did of course.

My hint: Take your recovery floppies to get into your host. For the case
you don't have some, take the installation floppies from some distro.

Best wishes
Frank
