Opening device files on a read-only file system works well for me. I've just
mounted a file system read-only, see this:
touch: foo: Read-only file system
rjc@lyta:/usr/src$ls -l null
crw-rw-rw- 1 root sys 1, 3 Aug 1 1997 null
rjc@lyta:/usr/src$cat /etc/passwd > null
Seems that read-only file systems only apply to real files. I have only tested
this with ReiserFS, but I believe that it's all VFS functionality and should
work in all file systems. If it doesn't then that's a kernel bug.
/dev can be mounted read-only if you don't need/want to change permissions etc.
For /etc, the fstab file is not a problem. mtab could be an issue, but it
could be a sym-link pointing elsewhere (so you re-mount root with the "-n"
option). If you use a service such as LDAP for authentication then you only
need an entry for root in /etc/passwd (and probably other system accounts).
User accounts don't need it. Of course changing the root password would be a

Alternatively if a daemon goes into an infinite loop writing error messages
(seen this happen with an old version of cfingerd and also with a commercial
LDAP server) then you don't want it to remove all space from /home, /database,
