You won't get far with an entirely RO filesystem: /var has to be writable 
(lock files, PID files, log files). It's probably try you can make /var on 
a ram disk and not log, but I don't think such a system will be very 
useful.

You CAN have / readonly; I've done it (mounted via NFS and it was exported 
RO). /etc has per-host configuration so can't be shared.
