+# 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.
