2 - trigger mounting; mounts might take time, need to be executed asynchronously in a forked process?
4 - need gc for active jobs that nothing cares for
6 - need gc for units that are not referenced anymore
8 - refreshing of units (i.e. reload config files)
10 - further dbusification (i.e. export dependency information, per-unit-type data)
16 - add a job mode which shuts everything down but what is requested
22 - create session/pgroup for child processes? handle input on console properly? interactive fsck? interactive luks password?
26 - templating/instances
28 - verify fragment data after loading: refuse cycles on yourself, service units contradicting, more than one Start executable, ...
30 - .socket needs to be notified not only by .service state changes, but also unsuccessful start jobs
32 - we probably cannot use glibc's syslog() for logging, since it
33 presumably uses the logging socket in blocking mode which might
34 trigger a deadlock if syslog does not process the socket anymore
35 (maybe because it is restarted) and the socket buffer is full.
37 - in udev/mount if properties change we need to delete the old
38 settings and install the new settings. Deleting the old settings is
41 - ability to kill services? i.e. in contrast to stopping them, go directly
44 - restart-on-success, restart-on-failure, restart-on-abort, restart-on-name-gnone
46 - port over to LISTEN_FDS/LISTEN_PID:
50 - rpcbind (/var/run/rpcbind.sock!)
57 - libvirtd (/var/run/libvirt/libvirt-sock-ro)
58 - bluetoothd (/var/run/sdp! @/org/bluez/audio!)
59 - avahi-daemon (/var/run/avahi-daemon/socket)
62 - teach dbus to talk to systemd when autospawning services
64 - unix sockets chown()/chgrp()
66 - watch dbus names for figuring out when a service has finished startup/goes down
68 - initialize console tty on startup
