[Michał Górny]

This is to fix bug #449102 and potentially future bugs from packages
using journald (are there any?).

+# Update the journald catalog. This needs to be called after installing
+# or removing catalog files.
+#
+# If systemd is not installed, no operation will be done. The catalog
+# will be (re)built once systemd is installed.
+#
+# See: http://www.freedesktop.org/wiki/Software/systemd/catalog

+	if [[ -x ${journalctl} ]]; then
+		ebegin "Updating systemd journal catalogs"
+		journalctl --update-catalog
+		eend $?
