Bug#562234: Cache file location in violation of FHS

If Debian wants to have a go at moving these files about, there are
settings available in lvm.conf to do that.

But it's an unnecessary overhead, not trivial to get the scripts right,
introduces new failure modes (and recovery paths) and you might do
better discussing revising the FHS to cater better for programs required
during startup.  At Red Hat we recently moved some multipath-tools data
from /var to /etc because it was causing us too many support problems.

Arguably the backup and archive files would be better stored in a
writeable non-lvm recovery-type partition (some folk may be happy with a
writeable /boot partition - I consider /boot should be read-only), as
you may want access to them in order to recover your root filesystem if
it's using LVM.

Last time I looked at the FHS it had not considered these "real world"
sorts of requirements so it seemed quite reasonable to me to override it
until someone improves it.
