[linux-lvm] LVM handling the entire physical disk

Disadvantage:

If the disk will/could ever be seen by another OS, it is better if the
alien OS knows there is some data (of unknown format) there via the
partition table.  This can help prevent accidental reformatting.

Advantage:

When mapping virtual disks to virtual machines, I find it especially
useful to bypass partition tables.  Using kpartx to access partitions
from the host is just another layer of complexity that doesn't buy you
anything.
