Bugfixes:
* Should systemctl status \* work on all unit types, not just .service?
10 years ago
* 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.
* ExecStart with unicode characters fails in strv_split_extract:

[Service]
Environment=ONE='one' "TWO='two two' too" THREE=
ExecStart=/bin/python3 -c 'import sys;print(sys.argv)' $ONE $TWO $THREE

* wiki: update journal format documentation for lz4 additions
Janitorial Clean-ups:
* Rearrange tests so that the various test-xyz.c match a specific src/basic/xyz.c again
7 years ago
Features:
* Add AddUser= setting to unit files, similar to DynamicUser=1 which however
creates a static, persistent user rather than a dynamic, transient user. We
can leverage code from sysusers.d for this.
* add some optional flag to ReadWritePaths= and friends, that has the effect
that we create the dir in question when the service is started. Example:
ReadWritePaths=:/var/lib/foobar
* sort generated hwdb files alphabetically when we import them, so that git
diffs remain minimal (in particular: the OUI databases we import are not
sorted, and not stable)
* set SystemCallArchitectures=native on all our services
* maybe add call sd_journal_set_block_timeout() or so to set SO_SNDTIMEO for
the sd-journal logging socket, and, if the timeout is set to 0, sets
O_NONBLOCK on it. That way people can control if and when to block for
logging.
* tighten sd_notify() MAINPID= checks a bit: don't accept foreign PIDs (i.e.
PIDs not managed by the service manager)
* journald: when we recv a log datagram via the native or syslog transports,
search for the PID in the active stream connections, and let's make sure to
always process the datagrams before the streams. Then, cache client metadata
per stream in the stream object. This way we can somewhat fix the race with
quickly exiting processes which log as long as they had their own stream
connection...
* hostnamed: populate form factor data from a new hwdb database, so that old
yogas can be recognized as "convertible" too, even if they predate the DMI
"convertible" form factor
* Maybe add a small tool invoked early at boot, that adds in or resizes
partitions automatically, to be used when the media used is actually larger
than the image written onto it is.
* Maybe add PrivatePIDs= as new unit setting, and do minimal PID namespacing
after all. Be strict however, only support the equivalent of nspawn's
--as-pid2 switch, and sanely proxy sd_notify() messages dropping stuff such
as MAINPID.
* change the dependency Set* objects in Unit structures to become Hashmap*, and
then store a bit mask who created a specific dependency: the source unit via
fragment configuration, the destination unit via fragment configuration, or
the source unit via udev rules (in case of .device units), or any combination
thereof. This information can then be used to flush out old udev-created
dependencies when the udev properties change, and eventually to implement a
"systemctl refresh" operation for reloading the configuration of individual
units without reloading the whole set.
* Add ExecMonitor= setting. May be used multiple times. Forks off a process in
the service cgroup, which is supposed to monitor the service, and when it
exits the service is considered failed by its monitor.
* track the per-service PAM process properly (i.e. as an additional control
process), so that it may be queried on the bus and everything.
* add a new "debug" job mode, that is propagated to unit_start() and for
services results in two things: we raise SIGSTOP right before invoking
execve() and turn off watchdog support. Then, use that to implement
"systemd-gdb" for attaching to the start-up of any system service in its
natural habitat.
* replace all canonicalize_file_name() invocations by chase_symlinks(), in
particulr those where a rootdir is relevant.
* maybe introduce gpt auto discovery for /var/tmp?
* set ProtectSystem=strict for all our usual services.
* fix PrivateNetwork= so that we fall back gracefully on kernels lacking
namespacing support (similar for the other namespacing options)
* maybe add gpt-partition-based user management: each user gets his own
LUKS-encrypted GPT partition with a new GPT type. A small nss module
enumerates users via udev partition enumeration. UIDs are assigned in a fixed
way: the partition index is added as offset to some fixed base uid. User name
is stored in GPT partition name. A PAM module authenticates the user via the
LUKS partition password. Benefits: strong per-user security, compatibility
with stateless/read-only/verity-enabled root. (other idea: do this based on
loopback files in /home, without GPT involvement)
* gpt-auto logic: introduce support for discovering /var matching an image. For
that, use a partition type UUID that is hashed from the OS name (as encoded
in /etc/os-release), the architecture, and 4 new bits from the gpt flags
field of the root partition. This way can easily support multiple OS
installations on the same GPT partition table, without problems with
unmatched /var partitions.
* gpt-auto logic: related to the above, maybe support a "secondary" root
partition, that is mounted to / and is writable, and where the actual root's
/usr is mounted into.
* machined: add apis to query /etc/machine-info data of a container
* .mount and .swap units: add Format=yes|no option that formats the partition before mounting/enabling it, implicitly
* gpt-auto logic: support encrypted swap, add kernel cmdline option to force it, and honour a gpt bit about it, plus maybe a configuration file
* drop nss-myhostname in favour of nss-resolve?
* drop internal dlopen() based nss-dns fallback in nss-resolve, and rely on the
external nsswitch.conf based one
* add a percentage syntax for TimeoutStopSec=, e.g. TimeoutStopSec=150%, and
then use that for the setting used in user@.service. It should be understood
relative to the configured default value.
* on cgroupsv2 add DelegateControllers=, to pick the precise cgroup controllers to delegate
* in networkd, when matching device types, fix up DEVTYPE rubbish the kernel passes to us
* enable LockMLOCK to take a percentage value relative to physical memory
* switch to ProtectSystem=strict for all our long-running services where that's possible
* Permit masking specific netlink APIs with RestrictAddressFamily=
* nspawn: start UID allocation loop from hash of container name
* nspawn: support that /proc, /sys/, /dev are pre-mounted
* define gpt header bits to select volatility mode
* ProtectKernelLogs= (drops CAP_SYSLOG, add seccomp for syslog() syscall, and DeviceAllow to /dev/kmsg) in service files
* ProtectClock= (drops CAP_SYS_TIMES, adds seecomp filters for settimeofday, adjtimex), sets DeviceAllow o /dev/rtc
* ProtectTracing= (drops CAP_SYS_PTRACE, blocks ptrace syscall, makes /sys/kernel/tracing go away)
* ProtectMount= (drop mount/umount/pivot_root from seccomp, disallow fuse via DeviceAllow, imply Mountflags=slave)
* ProtectKeyRing= to take keyring calls away
* RemoveKeyRing= to remove all keyring entries of the specified user
* ProtectReboot= that masks reboot() and kexec_load() syscalls, prohibits kill
on PID 1 with the relevant signals, and makes relevant files in /sys and
/proc (such as the sysrq stuff) unavailable
* DeviceAllow= should also generate seccomp filters for mknod()
* Add DataDirectory=, CacheDirectory= and LogDirectory= to match
RuntimeDirectory=, and create it as necessary when starting a service, owned by the right user.
* make sure the ratelimit object can deal with USEC_INFINITY as way to turn off things
* journalctl: make sure -f ends when the container indicated by -M terminates
* mount: automatically search for "main" partition of an image has multiple
partitions
* expose the "privileged" flag of ExecCommand on the bus, and open it up to
transient units
* in nss-systemd, if we run inside of RootDirectory= with PrivateUsers= set,
find a way to map the User=/Group= of the service to the right name. This way
a user/group for a service only has to exist on the host for the right
mapping to work.
* allow attaching additional journald log fields to cgroups
* add bus API for creating unit files in /etc, reusing the code for transient units
* add bus API to remove unit files from /etc
* add bus API to retrieve current unit file contents (i.e. implement "systemctl cat" on the bus only)
* rework fopen_temporary() to make use of open_tmpfile_linkable() (problem: the
kernel doesn't support linkat() that replaces existing files, currently)
* check if DeviceAllow= should split first, resolve specifiers later
* transient units: don't bother with actually setting unit properties, we
reload the unit file anyway
* journald: sigbus API via a signal-handler safe function that people may call
from the SIGBUS handler
* optionally, also require WATCHDOG=1 notifications during service start-up and shutdown
* resolved: when routing queries, make sure only look for the *longest* suffix...
* delay activation of logind until somebody logs in, or when /dev/tty0 pulls it
in or lingering is on (so that containers don't bother with it until PAM is used). also exit-on-idle
* cache sd_event_now() result from before the first iteration...
* add systemctl stop --job-mode=triggering that follows TRIGGERED_BY deps and adds them to the same transaction
* PID1: find a way how we can reload unit file configuration for
specific units only, without reloading the whole of systemd
* add an explicit parser for LimitRTPRIO= that verifies
the specified range and generates sane error messages for incorrect
specifications.
* do something about "/control" subcgroups in the unified cgroup hierarchy
* when we detect that there are waiting jobs but no running jobs, do something
* push CPUAffinity= also into the "cpuset" cgroup controller (only after the cpuset controller got ported to the unified hierarchy)
* PID 1 should send out sd_notify("WATCHDOG=1") messages (for usage in the --user mode, and when run via nspawn)
* 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
* man: document that unless you use StandardError=null the shell >/dev/stderr won't work in shell scripts in services
* 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 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?

* 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.

* "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)

* in systemctl list-unit-files: show the install value the presets would suggest for a service in a third column
7 years ago
* figure out when we can use the coarse timers
7 years ago
* 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

* systemd.show_status= should probably have a mode where only failed
units are shown.

* resolved:
- mDNS/DNS-SD
- service registration
- service/domain/types browsing
8 years ago
- avahi compat
8 years ago
- DNS-SD service registration from socket units
- 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.
- allow clients to request DNSSEC for a single lookup even if DNSSEC is off (?)
- hook up resolved with machined-based address resolution

8 years ago
* mount_cgroup_controllers(): symlinks need to get the label applied
8 years ago
* 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.

* gpt-auto-generator:

- Define new partition type for encrypted swap? Support probed LUKS for encrypted swap?
8 years ago
- Make /home automount rather than mount?
8 years ago
* 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
8 years ago
* MessageQueueMessageSize= (and suchlike) should use parse_iec_size().
8 years ago
8 years ago
* implement Distribute= in socket units to allow running multiple
service instances processing the listening socket, and open this up
for ReusePort=
8 years ago
* 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.
8 years ago
* 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
8 years ago
* cgroups:
- implement per-slice CPUFairScheduling=1 switch
- handle jointly mounted controllers correctly
- introduce high-level settings for RT budget, swappiness
- how to reset dynamically changed unit cgroup attributes sanely?
- when reloading configuration, apply new cgroup configuration
- when recursively showing the cgroup hierarchy, optionally also show
the hierarchies of child processes
8 years ago
* transient units:
- add field to transient units that indicate whether systemd or somebody else saves/restores its settings, for integration with libvirt
- ensure scope units may be started only a single time
8 years ago
* Automatically configure swap partition to use for hibernation by looking for largest swap partition on the root disk?
* when we detect low battery and no AC on boot, show pretty splash and refuse boot
* libsystemd-journal, libsystemd-login, libudev: add calls to easily attach these objects to sd-event event loops
* be more careful what we export on the bus as (usec_t) 0 and (usec_t) -1
8 years ago
* rfkill,backlight: we probably should run the load tools inside of the udev rules so that the state is properly initialized by the time other software sees it
8 years ago
* After coming back from hibernation reset hibernation swap partition using the /dev/snapshot ioctl APIs
8 years ago
* If we try to find a unit via a dangling symlink, generate a clean
error. Currently, we just ignore it and read the unit from the search
8 years ago
path anyway.
* refuse boot if /usr/lib/os-release is missing or /etc/machine-id cannot be set up

ReadOnlyDirectories=... for whitelisting files for a service.

7 years ago
- kdbus: process fd=-1 for incoming msgs
7 years ago
- port to sd-resolve for connecting to TCP dbus servers
- kdbus: maybe add controlling tty metadata fields
7 years ago
- see if we can introduce a new sd_bus_get_owner_machine_id() call to retrieve the machine ID of the machine of the bus itself
- when kdbus does not take our message without memfds, try again with memfds
8 years ago
- see if we can drop more message validation on the sending side
- add API to clone sd_bus_message objects
8 years ago
- make AddMatch calls on dbus1 transports async?

- dbus spec updates:
- kdbus mapping
- NameLost/NameAcquired obsolete
- GVariant
8 years ago
- path escaping

- test bloom filter generation indexes
7 years ago
- kdbus: introduce a concept of "send-only" connections
7 years ago
- kdbus: add counter for refused unicast messages that is passed out via the RECV ioctl. SImilar to the counter for dropped multicast messages we already have.
8 years ago
* sd-event
- allow multiple signal handlers per signal?
7 years ago
- document chaining of signal handler for SIGCHLD and child handlers
- define more intervals where we will shift wakeup intervals around in, 1h, 6h, 24h, ...
- generate a failure of a default event loop is executed out-of-thread
- maybe add support for inotify events
* investigate endianness issues of UUID vs. GUID
9 years ago
* dbus: when a unit failed to load (i.e. is in UNIT_ERROR state), we
should be able to safely try another attempt when the bus call LoadUnit() is invoked.

* add a pam module that passes the hdd passphrase into the PAM stack and then expires it, for usage by gdm auto-login.
* add a pam module that on password changes updates any LUKS slot where the password matches
9 years ago
* maybe add a generator that looks for "systemd.run=" on the kernel cmdline for container usercases...

- add 'set -e' to scripts in test/
- make stuff in test/ work with separate output dir
9 years ago
9 years ago
* seems that when we follow symlinks to units we prefer the symlink
destination path over /etc and /usr. We should not do that. Instead
9 years ago
/etc should always override /run+/usr and also any symlink
destination.
9 years ago
* when isolating, try to figure out a way how we implicitly can order
all units we stop before the isolating unit...
9 years ago
* teach ConditionKernelCommandLine= globs or regexes (in order to match foobar={no,0,off})
8 years ago
* BootLoaderSpec: Clarify that the kernel has to be in $BOOT. Clarify
that the boot loader should be installed to the ESP. Define a way
how an installer can figure out whether a BLS compliant boot loader
is installed.
9 years ago
9 years ago
* think about requeuing jobs when daemon-reload is issued? usecase:
the initrd issues a reload after fstab from the host is accessible
and we might want to requeue the mounts local-fs acquired through
that automatically.
9 years ago
* systemd-inhibit: make taking delay locks useful: support sending SIGINT or SIGTERM on PrepareForSleep()
* remove any syslog support from log.c — we probably cannot do this before split-off udev is gone for good
9 years ago
* shutdown logging: store to EFI var, and store to USB stick?
* think about window-manager-run-as-user-service problem: exit 0 → activate shutdown.target; exit != 0 → restart service
9 years ago
* merge unit_kill_common() and unit_kill_context()
9 years ago
9 years ago
* introduce ExecCondition= in services
9 years ago

* mount: turn dependency information from /proc/self/mountinfo into dependency information between systemd units.
9 years ago
9 years ago
* logind:
- logind: optionally, ignore idle-hint logic for autosuspend, block suspend as long as a session is around
- When we update the kernel all kind of hibernation should be prohibited until shutdown/reboot
- logind: wakelock/opportunistic suspend support
- Add pretty name for seats in logind
- logind: allow showing logout dialog from system?
9 years ago
- we should probably handle SIGTERM/SIGINT to not leave dot files around, just in case
8 years ago
- session scopes/user unit: add RequiresMountsFor for the home directory of the user
- add Suspend() bus calls which take timestamps to fix double suspend issues when somebody hits suspend and closes laptop quickly.
- if pam_systemd is invoked by su from a process that is outside of a
any session we should probably just become a NOP, since that's
usually not a real user session but just some system code that just
needs setuid().
- logind: make the Suspend()/Hibernate() bus calls wait for the for
the job to be completed. before returning, so that clients can wait
for "systemctl suspend" to finish to know when the suspending is
complete.
- logind: when the power button is pressed short, just popup a
logout dialog. If it is pressed for 1s, do the usual
shutdown. Inspiration are Macs here.
- expose "Locked" property on logind sesison objects
- given that logind now lets PID 1 do all nasty work, we can
probably reduce the capability set it retains substantially.
(we need CAP_SYS_ADMIN for drmSetMaster(), so maybe not worth it)
7 years ago
- expose orientation sensors and tablet mode through logind
- maybe allow configuration of the StopTimeout for session scopes
- 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.
- follow PropertiesChanged state more closely, to deal with quick logouts and
relogins

* service: watchdog logic: for testing purposes allow ping, but do not require pong
9 years ago
9 years ago
* journal:
7 years ago
- consider introducing implicit _TTY= + _PPID= + _EUID= + _EGID= + _FSUID= + _FSGID= fields
- import and delete pstore filesystem content at startup
9 years ago
- journald: also get thread ID from client, plus thread name
- journal: when waiting for journal additions in the client always sleep at least 1s or so, in order to minimize wakeups
- add API to close/reopen/get fd for journal client fd in libsystemd-journal.
- fallback to /dev/log based logging in libsystemd-journal, if we cannot log natively?
9 years ago
- declare the local journal protocol stable in the wiki interface chart
- sd-journal: speed up sd_journal_get_data() with transparent hash table in bg
- journald: when dropping msgs due to ratelimit make sure to write
"dropped %u messages" not only when we are about to print the next
message that works, but alraedy after a short tiemout
- check if we can make journalctl by default use --follow mode inside of less if called without args?
- maybe add API to send pairs of iovecs via sd_journal_send
9 years ago
- journal: add a setgid "systemd-journal" utility to invoke from libsystemd-journal, which passes fds via STDOUT and does PK access
9 years ago
- journactl: support negative filtering, i.e. FOOBAR!="waldo",
and !FOOBAR for events without FOOBAR.
- journal: store timestamp of journal_file_set_offline() int he header,
so it is possible to display when the file was last synced.
9 years ago
- journal-send.c, log.c: when the log socket is clogged, and we drop, count this and write a message about this when it gets unclogged again.
- journal: find a way to allow dropping history early, based on priority, other rules
- journal: When used on NFS, check payload hashes
- journald: add kernel cmdline option to disable ratelimiting for debug purposes
- refuse taking lower-case variable names in sd_journal_send() and friends.
- journald: we currently rotate only after MaxUse+MaxFilesize has been reached.
- journal: deal nicely with byte-by-byte copied files, especially regards header
- journal: sanely deal with entries which are larger than the individual file size, but where the components would fit
- Replace utmp, wtmp, btmp, and lastlog completely with journal
8 years ago
- journalctl: instead --after-cursor= maybe have a --cursor=XYZ+1 syntax?
- when a kernel driver logs in a tight loop, we should ratelimit that too.
- journald: optionally, log debug messages to /run but everything else to /var
- journald: when we drop syslog messages because the syslog socket is
full, make sure to write how many messages are lost as first thing
to syslog when it works again.
- journald: make sure ratelimit is actually really per-service with the new cgroup changes
- change systemd-journal-flush into a service that stays around during
boot, and causes the journal to be moved back to /run on shutdown,
so that we do not keep /var busy. This needs to happen synchronously,
8 years ago
hence doing this via signals is not going to work.
- optionally support running journald from the command line for testing purposes in external projects
- journald: allow per-priority and per-service retention times when rotating/vacuuming
- journald: make use of uid-range.h to managed uid ranges to split
journals in.
- journalctl: add the ability to look for the most recent process of a binary. journalctl /usr/bin/X11 --pid=-1 or so...
- improve journalctl performance by loading journal files
lazily. Encode just enough information in the file name, so that we
do not have to open it to know that it is not interesting for us, for
the most common operations.
- journal-or-kmsg is currently broken? See reverted
commit 4a01181e460686d8b4a543b1dfa7f77c9e3c5ab8.
- man: document that corrupted journal files is nothing to act on
- rework journald sigbus stuff to use mutex
- 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.
- journalctl --verify: don't show files that are currently being
written to as FAIL, but instead show that their are being written to.
- add journalctl -H that talks via ssh to a remote peer and passes through
binary logs data
- add a version of --merge which also merges /var/log/journal/remote
- log accumulated resource usage after each service invocation
- 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.
- assign MESSAGE_ID to log messages about failed services

* systemctl:
- add systemctl switch to dump transaction without executing it
- Add a verbose mode to "systemctl start" and friends that explains what is being done or not done
- "systemctl disable" on a static unit prints no message and does
nothing. "systemctl enable" does nothing, and gives a bad message
about it. Should fix both to print nice actionable messages.
- print nice message from systemctl --failed if there are no entries shown, and hook that into ExecStartPre of rescue.service/emergency.service
- add new command to systemctl: "systemctl system-reexec" which reexecs as many daemons as virtually possible
- systemctl enable: fail if target to alias into does not exist? maybe show how many units are enabled afterwards?

* 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.
- 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
- 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
- fix logic always print a final newline on output.
https://github.com/systemd/systemd/pull/272#issuecomment-113153176
- should optionally support receiving WATCHDOG=1 messages from its payload
PID 1...
- should send out sd_notify("WATCHDOG=1") messages
- optionally automatically add FORWARD rules to iptables whenever nspawn is
running, remove them when shut down.
- Improve error message when --bind= is used on a non-existing source
directory
- maybe make copying of /etc/resolv.conf optional, and skip it if --read-only
is used
* dissect
- refuse mounting over a mount point
- automatically discover .roothash files in dissect, similarly to nspawn
* machined:
- add an API so that libvirt-lxc can inform us about network interfaces being
removed or added to an existing machine
- "machinectl migrate" or similar to copy a container from or to a
difference host, via ssh
- 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)
- "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
* importd:
- generate a nice warning if mkfs.btrfs is missing

* cryptsetup:
- cryptsetup-generator: allow specification of passwords in crypttab itself
- move cryptsetup key caching into kernel keyctl?

* add option to sockets to avoid activation. Instead just drop packets/connections, see http://cyberelk.net/tim/2012/02/15/portreserve-systemd-solution/
