+* generator that automatically discovers btrfs subvolumes, identifies their purpose based on some xattr on them.
+
+* support setting empty environment variables with Environment= and EnvironmentFile=
+
+* machined/machinectl: sort IP addresses we return by scope and protocol
+* machined: write NSS module for looking up IP addresses for machines
+
+* timer units: actually add extra delays to timer units with high AccuracySec values, don't start them already when we are awake...
+
+* timesyncd - hookup with networkd: NTP servers from dhcp
+
+* a way for container managers to turn off getty starting via $container_headless= or so...
+
+* figure out a nice way how we can let the admin know what child/sibling unit causes cgroup membership for a specific unit
+
+* journalctl: add the ability to look for the most recent process of a binary. journalctl /usr/bin/X11 --pid=-1 or so...
+
+* set NOTIFY_SOCKET also for control processes
+
+* mount_cgroup_controllers(): symlinks need to get the label applied
+
+* For timer units: add some mechanisms so that timer units that trigger immediately on boot do not have the services
+ they run added to the initial transaction and thus confuse Type=idle.
+
+* Add timeout to early-boot, and shut down the system if it is hit. Solves the laptop-in-bag problem and is useful for embedded cases
+
+* Run most system services with cgroupfs read-only and procfs with a more secure mode (doesn't work, since the hidepid= option is per-pid-namespace, not per-mount)
+
+* sd-event: generate a failure of a default event loop is executed out-of-thread
+
+* 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?
