+* support transient mount units
+
+* Imply DevicePolicy=closed when PrivateDevices= is used
+
+* add an "input" group to udev logic and add all input devices to it
+
+* libsystemd-login: implement getpeer_unit(), get_peer_slice(), ...
+
+* 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.
