# During the migration of conffiles from apache2.2-common to apache2,
# some things may have gone wrong.
# * Some conffiles may have been left with obsolete content. These
# have an md5sum in this list.
# * Some other conffiles may have been removed but dpkg still thinks that
# they belong to apache2.2-common. A few of these have been re-introduced,
# but dpkg being confused about their state causes dpkg to think the
# admin has removed them and to not create the new content.
# These have a 'restore' instead of a md5 in the list.
