After discussion with Steve on IRC, it turns out that this is due
to using loop-aes-utils.  This package does not use libmount, and
so breaks due to trying to modify /etc/mtab (which has been a
symlink for some time).  All wheezy and later systems have /etc/mtab
as a symlink, making libmount a requirement.  loop-aes-utils must
use libmount for wheezy.

Given that loop-aes-utils is a fork of util-linux-ng from (it appears)
2009 from the NEWS file, it may be possible to merge in the subsequent
util-linux-ng changes.  Which would be a good idea anyway.


Regards,
Roger
