What would that mean for people who like to setup multi-boot
situations, though?  Will dragonfly require that all partitions
on a disk be dragonfly-format?  Could you go with GPT for the
initial partition table, and then store all the extra info that
you want at the start of each partition?

And as I sit here installing a new machine, I also wonder if you
should pick a different partition-type for Dragonfly, just so you
don't have to worry about matching future UFS/UFS2 changes.
