include _SYSTEMD_UNIT= fields so that "systemctl status" can show
them along with the unit
-* define a message ID for "overmounting non-empty directory" and write message catalog entry for it
-
* use polkit "imply" for binding hostname actions together
* journal: when waiting for journal additions always sleep at least 1s or so, in order to minimize wakeups
running side-by-side with journald. This usually indicates that the
syslog implementation has not been able to keep up with the speed of
messages queued.

+Subject: Mount point is not empty
+Defined-By: systemd
+Support: http://lists.freedesktop.org/mailman/listinfo/systemd-devel
+Documentation: http://www.freedesktop.org/wiki/Software/systemd/catalog/@MESSAGE_ID@
+
+The directory @WHERE@ is specified as the mount point (second field in
+/etc/fstab or Where= field in systemd unit file) and is not empty.
+This does not interfere with mounting, but the pre-exisiting files in
+this directory become inaccessible. To see those over-mounted files,
+please manually mount the underlying file system to a secondary
+location.
