I have a machine with several Debian systems on it -- one
that's stable, one that's tracking etch. Depending on how
critical the applications we need are, we boot one or the other.
Would each one end up with its own /etc/lvm file? Would they
have to be carefully synchronized? Or would each one create
its own by running vgscan to examine the physical volumes at
boot time? In which case the physical volumes must be marked
