 Features:
 

+* 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, ...
+
+* maybe add DefaultTimerAccuracySec= as global config option to set AccuracySec='s default value in .timer units
+
+* 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?
+
+* 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.
+
+* support transient mount units
+
+* Imply DevicePolicy=closed when PrivateDevices= is used. Mount
+  pts+kdbus+shm+mqueue into /dev namespace
+
+* add an "input" group to udev logic and add all input devices to it
+
+* machined: provide calls GetMachineByAddress() on the manager
+  interface to get the machine for a local IP address, and
+  GetAddress() on the Machine interface to get the Address for a
+  machine. Implement via forking off child process which quickly joins
+  the cotnainer and passes data to parent. Show this in "machinectl
+  status", and use it to implement NSS module to provide automatic
+  name resolution for containers.
+
+* add generator that pulls in systemd-network from containers when
+  CAP_NET_ADMIN is set, more than the loopback device is defined, even
+  when it is otherwise off
+
+* MessageQueueMessageSize= and RLimitFSIZE= (and suchlike) should use parse_iec_size().
+

 * "busctl status" works only as root on dbus1, since we cannot read
   /proc/$PID/exe

-* systemctl (and possibly related tools): support a new switch that
-  allows enumerating units in local containers recursively. "systemctl
-  list-units -R" or so should not only lists on the host, but also the
-  services in all containers in a pretty way, to give an overview of
-  the entire system. Also, maybe add "systemctl list-machines" which
-  works like "machinectl list" but includes information about the
-  health status of each registered machine. For that we should
-  probably implement something that encodes the system health status
-  in a single enum state, i.e. something like a system-wide state
-  starting → running → failed → stopping, that is based on the current
-  job queue and a check for failed services. Maybe then change
-  "systemctl status" without args to output this state along with a
-  selection of other data, such as the uptime or so.
-
-* generalize ConditionXYZ= logic and make it available in networkd's
-  .network, .netdev, .network files, too. This is particularly useful
-  to match on containers with ConditionVirtualization to
-  conditionalize network setups for containers
-
-* doc: remove documentation for .include, drop-in snippets are the
-  better replacement.
-
-* Add a seccomp-based filter for socket() calls to limit services to
-  specific address families (for example: AF_UNIX), inspired by
-  Android's sandboxing
+* systemctl: support --recursive for list-sockets, list-timers,
+  ... too, not just for list-units.

 
 * implement Distribute= in socket units to allow running multiple
   service instances processing the listening socket, and open this up
   for ReusePort=
