OK, in that case please forget my earlier remarks about possible hard
disk problems. If you made the root file system read-only yourself then
there is no indication of any problem.

I don't have any experience with that kind of situation. My best guess
is that you could use udev to have /dev in a (read-write) tmpfs, and you
will probably also need to make /tmp writable (in another ramdisk
maybe?). Hopefully somebody else has a better answer.
