    One thing that I have yet to see a conclusive answer to: Can I make LVM
    Logical Volumes from logical partitions in an extended physical volume.
      Since I have 4 physical volumes, including an extended volume, I would
    have to create the LVs from logical partitions.

    Also, assuming that I can use logical partitions, is it possible to use
    some, but not all logical partitions from an extended partition.
    Currently, my / partition is /dev/hda5 and my /boot partition is
    /dev/hda11 and I would want these to NOT be included in the LV. I would
    be including /dev/hda6 through /dev/hda10 as well as a new /dev/hda12
    (which will be the remaining space on the disk).

    Will this work?
