The following patch, using the configure options suggested by Alasdair
Kergon, reverts devmapper to the traditional and correct behaviour.
If there is no response by the weekend, I intend to NMU this.

Additionally, and more seriously, this breakage is also present in
the sarge release, and I would very much like to see this fixed in
sarge-proposed-updates.  The same patch to debian/rules should do
the job.  Would there be any objection to my submitting this fix?


Regards,
Roger
