Currently it must be at the beginning of a drive.

No, it's part of the drive.  In Vinum terminology, a "drive" is a disk
partition, the same one on which the subdisks are stored.

I'd suggest you take a look at the documentation at
http://www.vinumvm.org/cfbsd/vinum.pdf.  It should clarify a number of
things.

And yes, in retrospect it was a bad idea to put the configuration at
the front of the drive.
