    Thanks for the quick responses, guys. While the great and good are
    considering it, I may in the meantime throw caution to the wind and see if
    I can make some appropriately ad hoc changes to my own system. Any
    suggestions before I start butchering the file in question? Maybe since I
    no longer need more than 7 partitions per logical volume I should go back
    to using bsdlabel for the time being, although that feels too much like
    taking the easy way out. :)

    Chris.
