	So, has the metadata also been updated to have a version number
field in an easily found location?  This is a very unpleasant state of
affairs, and it will happen again if you haven't done this.

	This helps my peace of mind about doing the upgrade.  Perhaps
now I will do it with confidence that it will work and I'll get the
order of operations right.

	One question I have:

	Does it hurt for the old drivers to be in the kernel at the time
you run the upgrade script if none of the VGs are 'active'?

	I compiled LVM into my kernel instead of leaving it as a module,
so if it were a problem, I'd have to compile a new kernel that didn't
have the drivers.
