# 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.
