It really is getting /usr, /var and /tmp out of the way (them tmp
directories) and then getting to a state where system wide configuration
(/etc) is infrequent. The consequences will be the need to remount / to
be writable for any system changes like adding a user or changing a
config and then remounting read-only again.
Moving non boot services and their configs off / would help in this regard.
