@ -15,10 +15,6 @@ Bugfixes:
* properly handle .mount unit state tracking when two mount points are stacked one on top of another on the exact same mount point.
* shorten the message to sane length:
"Cannot add dependency job for unit display-manager.service, ignoring: Unit display-manager.service
failed to load: No such file or directory. See system logs and 'systemctl status display-manager.service' for details."
* sd_bus_unref() is broken regarding self-references and "pseudo thread-safety".
See the comment in sd_bus_unref() for more..
