The biggest problem with the /etc is /etc/mtab. If You can't write it,
then mount won't work.

So what? Under RC protection If you set special fd type on /etc, you have
to exclude /etc/mtab from that. This won't work since it will delete this
file and then recreate, so the special fd attribute is lost.
If you set the special fd on every file in the /etc dir, hm.. nice job..

So the simplest solution is to remove /etc/mtab, and simply symlink to
/proc/mounts.
rm /etc/mtab
ln -s /proc/mounts /etc/mtab

So if the /etc is read only, the system can start up. Of course you can
have problems with adjtime and so on, but these are not so critical
errors.
