-* add an "input" group to udev logic and add all input devices to it
+* add "M" as recursive version of "m" to tmpfiles, then use it for
+  chowning /run/log/journal (but not /var/log/journal), so that we
+  adjust the perms of journal files created before tmpfiles ran.
+
+* expose "Locked" property on logind sesison objects
+
+* add bus api to query unit file's X fields.
+
+* consider adding RuntimeDirectoryUser= + RuntimeDirectoryGroup=
+
+* sd-event: define more intervals where we will shift wakeup intervals around in, 1h, 6h, 24h, ...
+
+* gpt-auto-generator:
+  - Support LUKS for root devices
+  - Define new partition type for encrypted swap? Support probed LUKS for encrypted swap?
+  - Make /home automount rather than mount?

 
 

-* logind: watch drm connectors and if we see a number of connectors !=
-  1 avoid processing the lid switch.
+* improve journalctl performance by loading journal files
+  lazily. Encode just enough information in the file name, so that we
+  don't have to open it to know that it is not interesting for us, for
+  the most common operations.

 
 

-* logind: avoid processing the lid switch for 3min (or so) after
-  startup and 1min (or so) after coming back from suspend, in order to
-  give USB docking stations time to pop up a video device, which could
