+# postinst script for ceph

+# see: dh_installdeb(1)

+# summary of how this script can be called:
+#
+#      postinst configure <most-recently-configured-version>
+#      old-postinst abort-upgrade <new-version>
+#      conflictor's-postinst abort-remove in-favour <package> <new-version>
+#      postinst abort-remove
+#      deconfigured's-postinst abort-deconfigure in-favour <failed-install-package> <version> [<removing conflicting-package> <version>]
+#
+# The current action is to simply remove the mistakenly-added
+# /etc/init/ceph.conf file; this could be done in any of these cases,
+# although technically it will leave the system in a different state
+# than the original install that included that file.  So instead we
+# only remove on "configure", since that's the only time we know we're
+# successful in installing a newer package than the erroneous version.
+
+# for details, see http://www.debian.org/doc/debian-policy/ or
+# the debian-policy package
