+* logind: avoid suspending on SW_LID if SW_DOCK is set
+
+* MessageQueueMessageSize= and RLimitFSIZE= (and suchlike) should use parse_iec_size().
+
+* man: move .link, .network and .netdev documentation into their own
+ man pages maybe called "systemd.link(5)", "systemd.network(5)" and
+ "systemd.netdev(5)" or so.
+
+* "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.
+
+* Add a seccomp-based filter for socket() calls to limit services to
+ specific address families (for example: AF_UNIX), inspired by
+ Android's sandboxing
+
+* implement Distribute= in socket units to allow running multiple
+ service instances processing the listening socket, and open this up
+ for ReusePort=
+
+* add a timelimit to generator invocation
+
+* socket units: support creating sockets in different namespace,
+ opening it up for JoinsNamespaceOf=. This would require to fork off
+ a tiny process that joins the namespace and creates/binds the socket
+ and passes this back to PID1 via SCM_RIGHTS. This also could be used
+ to allow Chown/chgrp on sockets without requiring NSS in PID 1.
+
+* New service property: maximum CPU and wallclock runtime for a service
+
+* introduce bus call FreezeUnit(s, b), as well as "systemctl freeze
+ $UNIT" and "systemctl thaw $UNIT" as wrappers around this. The calls
+ should SIGSTOP all unit processes in a loop until all processes of
+ it are fully stopped. This can later be used for app management by
+ desktop UIs such as gnome-shell to freeze apps that are not visible
+ on screen, not unlike how job control works on the shell
+
+* completions:
+ - busctl zsh completion is outdated
+ - systemd-nspawn -Z/-L/-q is missing for zsh
+ - systemd-nspawn completion is missing for bash
+ - manager property enumeration was broken when systemd moved to /usr/lib/
