Bug#2160: dpkg conffile upgrades

[Robert Leslie <rob@advantage.org>]

Package: dpkg
Version: 1.0.10

dpkg will orphan conffiles which were previously part of a package but aren't
any longer.

For example: mount-2.5-4 no longer lists /etc/fstab.sample as a conffile (in
fact `conffiles' was removed altogether) yet dpkg leaves this file behind
when upgrading.

Can this be considered a bug in dpkg, or is the new package really responsible
for cleaning up the previous version's conffiles (say, via preinst)?

Thanks.
