Thanks for spotting this and letting me know.

Since lvm-snapshot is based upon block-device
(sbuild::chroot_lvm_snapshot derives from
sbuild::chroot_block_device_base) if you explicitly disable
block-device chroots, you'll break lvm-snapshot chroots as
a side-effect since it's not building the base class it is
derived from.

This likely just needs a small tweak to configure.ac and/or
the makefile to make sure all combinations work correctly.

Since both block-device and lvm-snapshot derive from
block_device_base it should be possible to configure
them independently now.  The only prerequisite is
liblockdev to handle the locking.

Regards,
Roger
