The correct fix is to change the configure options to libdevmapper1.01
as I articulated earlier.
My workaround is a patch to the init script provided by lvm-common:

I use ext3 over lvm with dump and amanda and am quite happy with the
results. No method operating on a live filesystem can be "perfect", but
this combination more than meets my current backup needs.

I don't currently use snapshots, so have no particular suggestions. Let
me know what you decide to do in the end.

I've never used xfs on a filesystem I needed to back up, so I don't have
anything to add here, either.
