 Bugfixes:

-* Should systemctl status \* work on all unit types, not just .service?

 
 

-* enabling an instance unit creates a pointless link, and
-  the unit will be started with getty@getty.service:
-    $ systemctl enable getty@.service
-    ln -s '/usr/lib/systemd/system/getty@.service' '/etc/systemd/system/getty.target.wants/getty@.service'
+* Should systemctl status \* work on all unit types, not just .service?

 
 * Dangling symlinks of .automount unit files in .wants/ directories, set up
   automount points even when the original .automount file did not exist
   anymore. Only the .mount unit was still around.

-* properly handle .mount unit state tracking when two mount points are stacked one on top of another on the exact same mount point.
-
-* shorten the message to sane length:
+* ExecStart with unicode characters fails in strv_split_extract:

 
 

-  Cannot add dependency job for unit display-manager.service, ignoring: Unit display-manager.service failed to load: No such file or directory. See system logs and 'systemctl status display-manager.service' for details.

-* systemctl --root=container/ set-default ... is totally borked.
-
-* sd_bus_unref() is broken regarding self-references and "pseudo thread-safety".
-  See the comment in sd_bus_unref() for more..
+* When systemctl --host is used, underlying ssh connection can remain open.
+  bus_close does not kill children?

 Features:
 
 
 Features:
 

-* sd-event: generate a failure of a default event loop is executed out-of-thread
+* sd-event: maybe add support for inotify events
+
+* 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...
+
+* 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.
+  http://lists.freedesktop.org/archives/systemd-devel/2015-June/032962.html
+
+* 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.
+  https://github.com/systemd/systemd/pull/272#issuecomment-113153176
+
+* make nspawn's --network-veth switch more powerful:
+  http://lists.freedesktop.org/archives/systemd-devel/2015-June/033121.html
+
+* 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
+
+* stop using off_t, it's a crazy type. Use uint64_t instead.
+
+* logind: follow PropertiesChanged state more closely, to deal with quick logouts and relogins
+
+* invent a better systemd-run scheme for naming scopes, that works with remoting
+
+* add journalctl -H that talks via ssh to a remote peer and passes through binary logs data
+
+* change journalctl -M to acquire fd to journal directory via machined, and then operate on that via openat() instead of absolute paths
+
+* add a version of --merge which also merges /var/log/journal/remote
+
+* log accumulated resource usage after each service invocation
+
+* nspawn: a nice way to boot up without machine id set, so that it is set at boot automatically for supporting --ephemeral. Maybe hash the host machine id together with the machine name to generate the machine id for the container
+
+* logind: rename session scope so that it includes the UID. THat way
+  the session scope can be arranged freely in slices and we don't have
+  make assumptions about their slice anymore.
+
+* journalctl: -m should access container journals directly by enumerating them via machined, and also watch containers coming and going. Benefit: nspawn --ephemeral would start working nicely with the journal.
+
+* nspawn: don't copy /etc/resolv.conf from host into container unless we are in shared-network mode
+
+* nspawn: optionally automatically add FORWARD rules to iptables whenever nspawn is running, remove them when shut down.
+
+* importd: generate a nice warning if mkfs.btrfs is missing
+
+* nspawn: add a logic for cleaning up read-only, hidden container images in /var/lib/machines that are not ancestors of any non-hidden containers
+
+* nspawn: Improve error message when --bind= is used on a non-existing source directory
+
+* nspawn: maybe make copying of /etc/resolv.conf optional, and skip it if --read-only is used
+
+* man: document how update dkr images works with machinectl
+  http://lists.freedesktop.org/archives/systemd-devel/2015-February/028630.html
+
+* nspawn: as soon as networkd has a bus interface, hook up --network-interface=, --network-bridge= with networkd, to trigger netdev creation should an interface be missing
+
+* rework C11 utf8.[ch] to use char32_t instead of uint32_t when referring
+  to unicode chars, to make things more expressive.
+
+* "machinectl migrate" or similar to copy a container from or to a
+  difference host, via ssh
+
+* tmpfiles: creating new directories/subvolumes/fifos/device nodes
+  should not follow symlinks. None of the other adjustment or creation
+  calls follow symlinks.
+
+* fstab-generator: default to tmpfs-as-root if only usr= is specified on the kernel cmdline
+
+* docs: bring http://www.freedesktop.org/wiki/Software/systemd/MyServiceCantGetRealtime up to date
+
+* mounting and unmounting mount points manually with different source
+  devices will result in collected collected on all devices used.
+  http://lists.freedesktop.org/archives/systemd-devel/2015-April/030225.html
+
+* add a job mode that will fail if a transaction would mean stopping
+  running units. Use this in timedated to manage the NTP service
+  state.
+  http://lists.freedesktop.org/archives/systemd-devel/2015-April/030229.html
+
+* Maybe add support for the equivalent of "ethtool advertise" to .link files?
+  http://lists.freedesktop.org/archives/systemd-devel/2015-April/030112.html
+
+* .timer units should optionally support CLOCK_BOOTTIME in addition to CLOCK_MONOTONIC
+
+* create a btrfs qgroup for /var/lib/machines, and add all container
+  subvolumes we create to it.
+
+* When logging about multiple units (stopping BoundTo units, conflicts, etc.),
+  log both units as UNIT=, so that journalctl -u triggers on both.
+
+* to allow "linking" of nspawn containers, extend --network-bridge= so
+  that it can dynamically create bridge interfaces that are refcounted
+  by the containers on them. For each group of containers to link together
+
+* journalctl --verify: don't show files that are currently being
+  written to as FAIL, but instead show that their are being written
+  to.
+
+* assign MESSAGE_ID to log messages about failed services
+
+* coredump: make the handler check /proc/$PID/rlimits for RLIMIT_CORE,
+  and supress coredump if turned off. Then change RLIMIT_CORE to
+  infinity by default for all services. This then allows per-service
+  control of coredumping.
+
+* generate better errors when people try to set transient properties
+  that are not supported...
+  http://lists.freedesktop.org/archives/systemd-devel/2015-February/028076.html
+
+* Introduce $LISTEN_NAMES to complement $LISTEN_FDS, containing a
+  colon separated list of identifiers for the fds passed.
+
+* maybe introduce WantsMountsFor=? Usecase:
+  http://lists.freedesktop.org/archives/systemd-devel/2015-January/027729.html
+
+* rework kexec logic to use new kexec_file_load() syscall, so that we
+  don't have to call kexec tool anymore.
+
+* The udev blkid built-in should expose a property that reflects
+  whether media was sensed in USB CF/SD card readers. This should then
+  be used to control SYSTEMD_READY=1/0 so that USB card readers aren't
+  picked up by systemd unless they contain a medium. This would mirror
+  the behaviour we already have for CD drives.
+
+* nspawn: emulate /dev/kmsg using CUSE and turn off the syslog syscall
+  with seccomp. That should provide us with a useful log buffer that
+  systemd can log to during early boot, and disconnect container logs
+  from the kernel's logs.
+
+* networkd/udev: implement SR_IOV configuration in .link files:
+  http://lists.freedesktop.org/archives/systemd-devel/2015-January/027451.html
+
+* When RLIMIT_NPROC is set from a unit file it currently always is set
+  for root, not for the user set in User=, which makes it
+  useless. After fixing this, set RLIMIT_NPROC for
+  systemd-journal-xyz, and all other of our services that run under
+  their own user ids, and use User= (but only in a world where userns
+  is ubiquitous since otherwise we cannot invoke those daemons on the
+  host AND in a container anymore). Also, if LimitNPROC= is used
+  without User= we should warn and refuse operation.
+
+* logind: maybe allow configuration of the StopTimeout for session scopes
+
+* Set NoNewPrivileges= on all of our own services, where that makes sense
+
+* Rework systemctl's GetAll property parsing to use the generic bus_map_all_properties() API
+
+* rework journald sigbus stuff to use mutex
+
+* import-dkr: support tarsum checksum verification, if it becomes reality one day...
+
+* import-dkr: convert json bits to nspawn configuration
+
+* core/cgroup: support net_cls modules, and support automatically allocating class ids, then add support for making firewall changes depending on it, to implement a per-service firewall
+
+* introduce systemd-nspawn-ephemeral@.service, and hook it into "machinectl start" with a new --ephemeral switch
+
+* "machinectl status" should also show internal logs of the container in question
+
+* "machinectl list-images" should show os-release data, as well as machine-info data (including deployment level)
+
+* Port various tools to make use of verbs.[ch], where applicable
+
+* "machinectl history"
+
+* "machinectl diff"
+
+* "machinectl commit" that takes a writable snapshot of a tree, invokes a shell in it, and marks it read-only after use
+
+* systemd-nspawn -x should support ephemeral instances of gpt images
+
+* hostnamectl: show root image uuid
+
+* sysfs set api in libudev is not const
+
+* Find a solution for SMACK capabilities stuff:
+  http://lists.freedesktop.org/archives/systemd-devel/2014-December/026188.html
+
+* port libmount hookup to use API's own inotify interface, as soon as that is table in libmount
+
+* "systemctl preset-all" should probably order the unit files it
+  operates on lexicographically before starting to work, in order to
+  ensure deterministic behaviour if two unit files conflict (like DMs
+  do, for example)
+
+* resolved should optionally register additional per-interface LLMNR
+  names, so that for the container case we can establish the same name
+  (maybe "host") for referencing the server, everywhere.
+
+* systemd-journal-upload (or a new, related tool): allow pushing out
+  journal messages onto the network in BSD syslog protocol,
+  continuously. Default to some link-local IP mcast group, to make this
+  useful as a one-stop debugging tool.

 
 

-* add "M" as recursive version of "m" to tmpfiles, then use it for
-  chowning /run/log/journal (but not /var/log/journal), so that we
-  adjust the perms of journal files created before tmpfiles ran.
+* synchronize console access with BSD locks:
+  http://lists.freedesktop.org/archives/systemd-devel/2014-October/024582.html

 
 

-* expose "Locked" property on logind sesison objects
+* as soon as we have kdbus, and sender timestamps, revisit coalescing multiple parallel daemon reloads:
+  http://lists.freedesktop.org/archives/systemd-devel/2014-December/025862.html
+
+* the install state probably shouldn't get confused by generated units, think dbus1/kdbus compat!
+
+* in systemctl list-unit-files: show the install value the presets would suggest for a service in a third column
+
+* figure out when we can use the coarse timers
+
+* add "systemctl start -v foobar.service" that shows logs of a service
+  while the start command runs. This is non-trivial to do without
+  races though, since we should flush out all journal messages before
+  returning from the "systemctl stop".
+
+* firstboot: make it useful to be run immediately after yum --installroot to set up a machine. (most specifically, make --copy-root-password work even if /etc/passwd already exists
+
+* timesyncd + resolved: add ugly bus calls to set NTP and DNS servers per-interface, for usage by NM
+
+* add infrastructure to allocate dynamic/transient users and UID ranges, for use in user-namespaced containers, per-seat gdm login screens and gdm guest sessions
+
+* machined: add an API so that libvirt-lxc can inform us about network interfaces being removed or added to an existing machine
+
+* maybe add support for specifier expansion in user.conf, specifically DefaultEnvironment=
+
+* code cleanup: retire FOREACH_WORD_QUOTED, port to extract_first_word() loops instead
+
+* introduce systemd-timesync-wait.service or so to sync on an NTP fix?
+
+* systemd --user should issue sd_notify() upon reaching basic.target, not on becoming idle
+
+* consider showing the unit names during boot up in the status output, not just the unit descriptions
+
+* dhcp: do we allow configuring dhcp routes on interfaces that are not the one we got the dhcp info from?
+
+* maybe allow timer units with an empty Units= setting, so that they
+  can be used for resuming the system but nothing else.
+
+* what to do about udev db binary stability for apps? (raw access is not an option)
+
+* maybe provide an API to allow migration of foreign PIDs into existing scopes.
+
+* maybe support a new very "soft" reboot mode, that simply kills all processes, disassembles everything, flushes /run and sysvipc, and then reexecs systemd again
+
+* man: document that corrupted journal files is nothing to act on
+
+* man: maybe use the word "inspect" rather than "introspect"?
+
+* "machinectl list" should probably show columns for OS version and IP addresses
+
+* systemctl: if some operation fails, show log output?
+
+* systemctl edit:
+- allow creation of units from scratch
+- use equvalent of cat() to insert existing config as a comment, prepended with #.
+  Upon editor exit, lines with one # are removed, lines with two # are left with one #, etc.
+
+* refcounting in sd-resolve is borked
+
+* exponential backoff in timesyncd and resolved when we cannot reach a server
+
+* extract_many_words() should probably be used by a lot of code that
+  currently uses FOREACH_WORD and friends. For example, most conf
+  parsing callbacks should use it.
+
+* merge ~/.local/share and ~/.local/lib into one similar /usr/lib and /usr/share....
+
+* systemd.show_status= should probably have a mode where only failed
+  units are shown.
+
+* add systemd.abort_on_kill or some other such flag to send SIGABRT instead of SIGKILL
+  (throughout the codebase, not only PID1)
+
+* networkd:
+  - add LLDP client side support
+  - the DHCP lease data (such as NTP/DNS) is still made available when
+    a carrier is lost on a link. It should be removed instantly.
+  - expose in the API the following bits:
+        - option 15, domain name and/or option 119, search list
+        - option 12, host name and/or option 81, fqdn
+        - option 123, 144, geolocation
+        - option 252, configure http proxy (PAC/wpad)
+  - provide a way to define a per-network interface default metric value
+    for all routes to it. possibly a second default for DHCP routes.
+  - allow Name= to be specified repeatedly in the [Match] section. Maybe also
+    support Name=foo*|bar*|baz ?
+  - duplicate address check for static IPs (like ARPCHECK in network-scripts)
+  - allow DUID/IAID to be customized, see issue #394.
+  - support configuration option for TSO (tcp segmentation offload)
+  - networkd: whenever uplink info changes, make DHCP server send out FORCERENEW
+
+* resolved:
+  - put networkd events and rtnl events at a higher priority, so that
+    we always process them before we process client requests
+  - DNSSEC
+        - add display of private key types (http://tools.ietf.org/html/rfc4034#appendix-A.1.1)?
+  - DNS
+        - search paths
+  - mDNS/DNS-SD
+        - avahi compat
+  - DNS-SD service registration from socket units
+  - edns0
+  - dname: Not necessary for plain DNS as synthesized cname is handed out instead if we do not
+           announce dname support. However, for DNSSEC it is necessary as the synthesized cname
+           will not be signed.
+  - cname on PTR (?)
+
+* Allow multiple ExecStart= for all Type= settings, so that we can cover rescue.service nicely
+
+* Add a new verb "systemctl top"
+
+* add new gpt type for btrfs volumes
+
+* support empty /etc boots nicely:
+  - nspawn/gpt-generator: introduce new gpt partition type for /usr
+  - fstab-generator: support systemd.volatile=yes|no|state on the kernel cmdline, too, similar to nspawn's --volatile=
+
+* generator that automatically discovers btrfs subvolumes, identifies their purpose based on some xattr on them.
+
+* timer units: actually add extra delays to timer units with high AccuracySec values, don't start them already when we are awake...
+
+* a way for container managers to turn off getty starting via $container_headless= or so...
+
+* figure out a nice way how we can let the admin know what child/sibling unit causes cgroup membership for a specific unit
+
+* mount_cgroup_controllers(): symlinks need to get the label applied
+
+* For timer units: add some mechanisms so that timer units that trigger immediately on boot do not have the services
+  they run added to the initial transaction and thus confuse Type=idle.
+
+* Run most system services with cgroupfs read-only and procfs with a more secure mode (doesn't work, since the hidepid= option is per-pid-namespace, not per-mount)
+
+* sd-event: generate a failure of a default event loop is executed out-of-thread

 
 * add bus api to query unit file's X fields.
