This particular box has existing EVMS snapshots, LVM containers and LVM2
containers, so (although a bit of a mess, which I'd like to sort out)
it's easier to manage through one tool than two.  I also know how to use
EVMS but not LVM2 directly, so that's what I was hoping to do.  However,
I guess I could migrate it completely over to LVM2 if I had to.
