Opinions: root mirror recovery

[Doug Hughes]

There are three variations of disaster recovery scripts on the ssa-managers
web page. They have various degrees of granularity. One requires that you
have 'exactly' the same configuration after the disaster (# disks, size of
disks, # cylinders, etc). Another only requires that you have roughly same
amount of space or more, and creates volumes at about the same size as
before (within about 250MB). The third is somewhere in between.
