+* PID 1 should send out sd_notify("WATCHDOG=1") messages (for usage in the --user mode, and when run via nspawn)
+
+* nspawn should send out sd_notify("WATCHDOG=1") messages
+
+* nspawn should optionally support receiving WATCHDOG=1 messages from its payload PID 1...
+
+* introduce "machinectl shell" that is like systemd-run -M foo /bin/bash -t but also adds PAMName=login
+
+* allow loging into host with "machinectl login".
+
+* consider throwing a warning if a service declares it wants to be "Before=" a .device unit.
+
+* "systemctl edit" should know a mode to create a new unit file
+
+* there's probably something wrong with having user mounts below /sys,
+ as we have for debugfs. for exmaple, src/core/mount.c handles mounts
+ prefixed with /sys generally special.

+
+* Add PassEnvironment= setting to service units, to import select env vars from PID 1 into the service env block
+
+* nspawn: fix logic always print a final newline on output.

+
+* make nspawn's --network-veth switch more powerful:

+
+* man: document that unless you use StandardError=null the shell >/dev/stderr won't work in shell scripts in services
+
+* man: clarify that "machinectl show" shows different information than "machinectl status" (no cgroup tree, no IP addresses, ...)
+
+* "systemctl daemon-reload" should result in /etc/systemd/system.conf being reloaded by systemd
+
+* install: include generator dirs in unit file search paths
