Another avenue that you might want to explore is changing the mount
options so that nothing is written to the drive unless you intend it.
i.e. Ignoring updating "access times", etc. That lets you keep things
writable, if you'd like to do so.
I don't think you can put /etc/ on another device. But you definitely
can mount /var/ from another location. /var/, /usr/, and few others can
easily be mounted from other drives just the same as they can be on
other partitions on a hard drive.
