During the "do stuff" phase, /usr is also writeable, which is undesirable on production systems. That's the *original* problem with merging a read-only /usr with /.

I have about 6 or 7 backup jobs that run during the night and parse /etc/mtab to see if they need to place a copy of the backup onto an external medium. These examine the mount options and don't understand the non-standard options offered by Linux in /proc/mounts.
