Re: read-only root and usr partitions

It's best for now to mount root for write and /usr read-only. Under
normal operations I think the files in /etc are only written at
system start-up and shut-down (and during backups) and it might be
possible to have root read-only at other times. The _dates_ in /dev
are changed but the actual files are not except for the case of named
pipes or unix-domain sockets that are created there by some daemons
(lpd?). I think that stuff belongs in /tmp, not /dev.

I think it's desirable to be able to run with a read-only root, especially
since we are so close to being able to do it now, but it's not my highest
priority. I'd be interested in seeing others work on it.
