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. Thanks Bruce -- Can you get your operating system fixed when you need it?
