TODO revision 8477107dec4c89e2b85dfbf92051d96dd4f51480
4d6be67a34a8652a5fb6e2c2d9f57387e2a686c4Allan Foster* Should systemctl status \* work on all unit types, not just .service?
4d6be67a34a8652a5fb6e2c2d9f57387e2a686c4Allan Foster* enabling an instance unit creates a pointless link, and
4d6be67a34a8652a5fb6e2c2d9f57387e2a686c4Allan Foster the unit will be started with getty@getty.service:
4d6be67a34a8652a5fb6e2c2d9f57387e2a686c4Allan Foster $ systemctl enable getty@.service
4d6be67a34a8652a5fb6e2c2d9f57387e2a686c4Allan Foster ln -s '/usr/lib/systemd/system/getty@.service' '/etc/systemd/system/getty.target.wants/getty@.service'
4d6be67a34a8652a5fb6e2c2d9f57387e2a686c4Allan Foster* Dangling symlinks of .automount unit files in .wants/ directories, set up
4d6be67a34a8652a5fb6e2c2d9f57387e2a686c4Allan Foster automount points even when the original .automount file did not exist
4d6be67a34a8652a5fb6e2c2d9f57387e2a686c4Allan Foster anymore. Only the .mount unit was still around.
4d6be67a34a8652a5fb6e2c2d9f57387e2a686c4Allan Foster* properly handle .mount unit state tracking when two mount points are stacked one on top of another on the exact same mount point.
4d6be67a34a8652a5fb6e2c2d9f57387e2a686c4Allan Foster* shorten the message to sane length:
4d6be67a34a8652a5fb6e2c2d9f57387e2a686c4Allan Foster 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.
4d6be67a34a8652a5fb6e2c2d9f57387e2a686c4Allan Foster* sd_bus_unref() is broken regarding self-references and "pseudo thread-safety".
4d6be67a34a8652a5fb6e2c2d9f57387e2a686c4Allan Foster See the comment in sd_bus_unref() for more..
4d6be67a34a8652a5fb6e2c2d9f57387e2a686c4Allan Foster* Fedora: when installing fedora with yum --installroot /var/run is a directory, not a symlink
4d6be67a34a8652a5fb6e2c2d9f57387e2a686c4Allan Foster https://bugzilla.redhat.com/show_bug.cgi?id=975864
4d6be67a34a8652a5fb6e2c2d9f57387e2a686c4Allan Foster* Fedora: add an rpmlint check that verifies that all unit files in the RPM are listed in %systemd_post macros.
4d6be67a34a8652a5fb6e2c2d9f57387e2a686c4Allan Foster* Fedora: post FPC ticket to move add %tmpfiles_create to the packaging guidelines
4d6be67a34a8652a5fb6e2c2d9f57387e2a686c4Allan Foster* systemd-notify: fake ucred of msg to PID of parent, if that works, with fallback to our own if it doesn't.
4d6be67a34a8652a5fb6e2c2d9f57387e2a686c4Allan Foster* machined: make sure we can restart machined without losing machines
4d6be67a34a8652a5fb6e2c2d9f57387e2a686c4Allan Foster* machined/machinectl: sort IP addresses we return by scope and protocol
4d6be67a34a8652a5fb6e2c2d9f57387e2a686c4Allan Foster* machined: write NSS module for looking up IP addresses for machines
4d6be67a34a8652a5fb6e2c2d9f57387e2a686c4Allan Foster* timer units: actually add extra delays to timer units with high AccuracySec values, don't start them already when we are awake...
4d6be67a34a8652a5fb6e2c2d9f57387e2a686c4Allan Foster - hookup with networkd: NTP servers from dhcp
4d6be67a34a8652a5fb6e2c2d9f57387e2a686c4Allan Foster* a way for container managers to turn off getty starting via $container_headless= or so...
4d6be67a34a8652a5fb6e2c2d9f57387e2a686c4Allan Foster* figure out a nice way how we can let the admin know what child/sibling unit causes cgroup membership for a specific unit
4d6be67a34a8652a5fb6e2c2d9f57387e2a686c4Allan Foster* add a kernel command line option to enable the debug shell
4d6be67a34a8652a5fb6e2c2d9f57387e2a686c4Allan Foster* journalctl: add the ability to look for the most recent process of a binary. journalctl /usr/bin/X11 --pid=-1 or so...
4d6be67a34a8652a5fb6e2c2d9f57387e2a686c4Allan Foster* set NOTIFY_SOCKET also for control processes
4d6be67a34a8652a5fb6e2c2d9f57387e2a686c4Allan Foster* drop parsing of chkconfig header lines from service.c
4d6be67a34a8652a5fb6e2c2d9f57387e2a686c4Allan Foster* mount_cgroup_controllers(): symlinks need to get the label applied
4d6be67a34a8652a5fb6e2c2d9f57387e2a686c4Allan Foster* 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. Alternatively, split up the boot-up state into two, and make Type=idle only be affected by jobs for the default target, but ignore any further jobs
4d6be67a34a8652a5fb6e2c2d9f57387e2a686c4Allan Foster* Add RPM macros for registering/unregistering binfmt drop-ins
4d6be67a34a8652a5fb6e2c2d9f57387e2a686c4Allan Foster* Add timeout to early-boot, and shut down the system if it is hit. Solves the laptop-in-bag problem and is useful for embedded cases
4d6be67a34a8652a5fb6e2c2d9f57387e2a686c4Allan Foster* sd-resolve: add callback api
4d6be67a34a8652a5fb6e2c2d9f57387e2a686c4Allan Foster* ImmutableSystem=yes/no or so to mount /usr, /boot read-only/invisible, and leave /var and /etc writable
4d6be67a34a8652a5fb6e2c2d9f57387e2a686c4Allan Foster* InaccessibleHome=yes/no or so to hide /home and /run/user from a service
4d6be67a34a8652a5fb6e2c2d9f57387e2a686c4Allan Foster* Run most system services with cgroupfs read-only and procfs with a more secure mode
4d6be67a34a8652a5fb6e2c2d9f57387e2a686c4Allan Foster* sd-event: generate a failure of a default event loop is executed out-of-thread
4d6be67a34a8652a5fb6e2c2d9f57387e2a686c4Allan Foster* add "M" as recursive version of "m" to tmpfiles, then use it for
4d6be67a34a8652a5fb6e2c2d9f57387e2a686c4Allan Foster chowning /run/log/journal (but not /var/log/journal), so that we
4d6be67a34a8652a5fb6e2c2d9f57387e2a686c4Allan Foster adjust the perms of journal files created before tmpfiles ran.
4d6be67a34a8652a5fb6e2c2d9f57387e2a686c4Allan Foster* expose "Locked" property on logind sesison objects
4d6be67a34a8652a5fb6e2c2d9f57387e2a686c4Allan Foster* add bus api to query unit file's X fields.
4d6be67a34a8652a5fb6e2c2d9f57387e2a686c4Allan Foster* consider adding RuntimeDirectoryUser= + RuntimeDirectoryGroup=
4d6be67a34a8652a5fb6e2c2d9f57387e2a686c4Allan Foster* sd-event: define more intervals where we will shift wakeup intervals around in, 1h, 6h, 24h, ...
4d6be67a34a8652a5fb6e2c2d9f57387e2a686c4Allan Foster* gpt-auto-generator:
4d6be67a34a8652a5fb6e2c2d9f57387e2a686c4Allan Foster - Support LUKS for root devices
4d6be67a34a8652a5fb6e2c2d9f57387e2a686c4Allan Foster - Define new partition type for encrypted swap? Support probed LUKS for encrypted swap?
4d6be67a34a8652a5fb6e2c2d9f57387e2a686c4Allan Foster - Make /home automount rather than mount?
4d6be67a34a8652a5fb6e2c2d9f57387e2a686c4Allan Foster* improve journalctl performance by loading journal files
4d6be67a34a8652a5fb6e2c2d9f57387e2a686c4Allan Foster lazily. Encode just enough information in the file name, so that we
4d6be67a34a8652a5fb6e2c2d9f57387e2a686c4Allan Foster do not have to open it to know that it is not interesting for us, for
4d6be67a34a8652a5fb6e2c2d9f57387e2a686c4Allan Foster the most common operations.
4d6be67a34a8652a5fb6e2c2d9f57387e2a686c4Allan Foster* support transient mount units
4d6be67a34a8652a5fb6e2c2d9f57387e2a686c4Allan Foster* add an "input" group to udev logic and add all input devices to it
4d6be67a34a8652a5fb6e2c2d9f57387e2a686c4Allan Foster* machined: provide calls GetMachineByAddress() on the manager
4d6be67a34a8652a5fb6e2c2d9f57387e2a686c4Allan Foster interface to get the machine for a local IP address, and
4d6be67a34a8652a5fb6e2c2d9f57387e2a686c4Allan Foster GetAddress() on the Machine interface to get the Address for a
4d6be67a34a8652a5fb6e2c2d9f57387e2a686c4Allan Foster machine. Implement via forking off child process which quickly joins
4d6be67a34a8652a5fb6e2c2d9f57387e2a686c4Allan Foster the cotnainer and passes data to parent. Show this in "machinectl
4d6be67a34a8652a5fb6e2c2d9f57387e2a686c4Allan Foster status", and use it to implement NSS module to provide automatic
4d6be67a34a8652a5fb6e2c2d9f57387e2a686c4Allan Foster name resolution for containers.
4d6be67a34a8652a5fb6e2c2d9f57387e2a686c4Allan Foster* add generator that pulls in systemd-network from containers when
4d6be67a34a8652a5fb6e2c2d9f57387e2a686c4Allan Foster CAP_NET_ADMIN is set, more than the loopback device is defined, even
4d6be67a34a8652a5fb6e2c2d9f57387e2a686c4Allan Foster when it is otherwise off
4d6be67a34a8652a5fb6e2c2d9f57387e2a686c4Allan Foster* MessageQueueMessageSize= and RLimitFSIZE= (and suchlike) should use parse_iec_size().
4d6be67a34a8652a5fb6e2c2d9f57387e2a686c4Allan Foster* "busctl status" works only as root on dbus1, since we cannot read
4d6be67a34a8652a5fb6e2c2d9f57387e2a686c4Allan Foster* implement Distribute= in socket units to allow running multiple
4d6be67a34a8652a5fb6e2c2d9f57387e2a686c4Allan Foster service instances processing the listening socket, and open this up
4d6be67a34a8652a5fb6e2c2d9f57387e2a686c4Allan Foster for ReusePort=
4d6be67a34a8652a5fb6e2c2d9f57387e2a686c4Allan Foster* socket units: support creating sockets in different namespace,
4d6be67a34a8652a5fb6e2c2d9f57387e2a686c4Allan Foster opening it up for JoinsNamespaceOf=. This would require to fork off
4d6be67a34a8652a5fb6e2c2d9f57387e2a686c4Allan Foster a tiny process that joins the namespace and creates/binds the socket
4d6be67a34a8652a5fb6e2c2d9f57387e2a686c4Allan Foster and passes this back to PID1 via SCM_RIGHTS. This also could be used
4d6be67a34a8652a5fb6e2c2d9f57387e2a686c4Allan Foster to allow Chown/chgrp on sockets without requiring NSS in PID 1.
4d6be67a34a8652a5fb6e2c2d9f57387e2a686c4Allan Foster* New service property: maximum CPU and wallclock runtime for a service
4d6be67a34a8652a5fb6e2c2d9f57387e2a686c4Allan Foster* introduce bus call FreezeUnit(s, b), as well as "systemctl freeze
4d6be67a34a8652a5fb6e2c2d9f57387e2a686c4Allan Foster $UNIT" and "systemctl thaw $UNIT" as wrappers around this. The calls
4d6be67a34a8652a5fb6e2c2d9f57387e2a686c4Allan Foster should SIGSTOP all unit processes in a loop until all processes of
4d6be67a34a8652a5fb6e2c2d9f57387e2a686c4Allan Foster it are fully stopped. This can later be used for app management by
4d6be67a34a8652a5fb6e2c2d9f57387e2a686c4Allan Foster desktop UIs such as gnome-shell to freeze apps that are not visible
4d6be67a34a8652a5fb6e2c2d9f57387e2a686c4Allan Foster on screen, not unlike how job control works on the shell
4d6be67a34a8652a5fb6e2c2d9f57387e2a686c4Allan Foster* completions:
4d6be67a34a8652a5fb6e2c2d9f57387e2a686c4Allan Foster - manager property enumeration was broken when systemd moved to /usr/lib/
4d6be67a34a8652a5fb6e2c2d9f57387e2a686c4Allan Foster - implement per-slice CPUFairScheduling=1 switch
4d6be67a34a8652a5fb6e2c2d9f57387e2a686c4Allan Foster - handle jointly mounted controllers correctly
4d6be67a34a8652a5fb6e2c2d9f57387e2a686c4Allan Foster - introduce high-level settings for RT budget, swappiness
4d6be67a34a8652a5fb6e2c2d9f57387e2a686c4Allan Foster - how to reset dynamically changed unit cgroup attributes sanely?
4d6be67a34a8652a5fb6e2c2d9f57387e2a686c4Allan Foster - when reloading configuration, apply new cgroup configuration
4d6be67a34a8652a5fb6e2c2d9f57387e2a686c4Allan Foster - when recursively showing the cgroup hierarchy, optionally also show
4d6be67a34a8652a5fb6e2c2d9f57387e2a686c4Allan Foster the hierarchies of child processes
4d6be67a34a8652a5fb6e2c2d9f57387e2a686c4Allan Foster* transient units:
4d6be67a34a8652a5fb6e2c2d9f57387e2a686c4Allan Foster - allow creating auxiliary units with the same call
4d6be67a34a8652a5fb6e2c2d9f57387e2a686c4Allan Foster - add field to transient units that indicate whether systemd or somebody else saves/restores its settings, for integration with libvirt
4d6be67a34a8652a5fb6e2c2d9f57387e2a686c4Allan Foster - ensure scope units may be started only a single time
4d6be67a34a8652a5fb6e2c2d9f57387e2a686c4Allan Foster* Automatically configure swap partition to use for hibernation by looking for largest swap partition on the root disk?
4d6be67a34a8652a5fb6e2c2d9f57387e2a686c4Allan Foster* when we detect low battery and no AC on boot, show pretty splash and refuse boot
4d6be67a34a8652a5fb6e2c2d9f57387e2a686c4Allan Foster* machined, localed: when we try to kill an empty cgroup, generate an ESRCH error over the bus
4d6be67a34a8652a5fb6e2c2d9f57387e2a686c4Allan Foster* libsystemd-journal, libsystemd-login, libudev: add calls to easily attach these objects to sd-event event loops
4d6be67a34a8652a5fb6e2c2d9f57387e2a686c4Allan Foster* be more careful what we export on the bus as (usec_t) 0 and (usec_t) -1
4d6be67a34a8652a5fb6e2c2d9f57387e2a686c4Allan Foster* unify dispatch table in systemctl_main() and friends
4d6be67a34a8652a5fb6e2c2d9f57387e2a686c4Allan Foster* Automatically configure swap partition to use for hibernation by looking for largest swap partition on the root disk?
4d6be67a34a8652a5fb6e2c2d9f57387e2a686c4Allan Foster* socket-proxyd: Use sd-resolve to resolve the server address
4d6be67a34a8652a5fb6e2c2d9f57387e2a686c4Allan Foster* 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
4d6be67a34a8652a5fb6e2c2d9f57387e2a686c4Allan Foster* After coming back from hibernation reset hibernation swap partition using the /dev/snapshot ioctl APIs
4d6be67a34a8652a5fb6e2c2d9f57387e2a686c4Allan Foster* If we try to find a unit via a dangling symlink, generate a clean
4d6be67a34a8652a5fb6e2c2d9f57387e2a686c4Allan Foster error. Currently, we just ignore it and read the unit from the search
4d6be67a34a8652a5fb6e2c2d9f57387e2a686c4Allan Foster path anyway.
4d6be67a34a8652a5fb6e2c2d9f57387e2a686c4Allan Foster* refuse boot if /etc/os-release is missing or /etc/machine-id cannot be set up
4d6be67a34a8652a5fb6e2c2d9f57387e2a686c4Allan Foster* given that logind now lets PID 1 do all nasty work, we can
4d6be67a34a8652a5fb6e2c2d9f57387e2a686c4Allan Foster probably reduce the capability set it retains substantially.
4d6be67a34a8652a5fb6e2c2d9f57387e2a686c4Allan Foster (we need CAP_SYS_ADMIN for drmSetMaster(), so maybe not worth it)
4d6be67a34a8652a5fb6e2c2d9f57387e2a686c4Allan Foster* btrfs raid assembly: some .device jobs stay stuck in the queue
4d6be67a34a8652a5fb6e2c2d9f57387e2a686c4Allan Foster* make sure gdm does not use multi-user-x but the new default X configuration file, and then remove multi-user-x from systemd
4d6be67a34a8652a5fb6e2c2d9f57387e2a686c4Allan Foster* man: the documentation of Restart= currently is very misleading and suggests the tools from ExecStartPre= might get restarted.
- introduce sd_bus_emit_object_added()/sd_bus_emit_object_removed() that automatically includes the build-in interfaces in the list
- .busname units should not use get_user_creds()/get_cgroup_creds() but instead do NSS only in temporarily forked off child
- kdbus: matches against source or destination pids for an "strace -p"-like feel. Problem: The PID info needs to be available in userspace too...
- NameLost/NameAcquired obsolete
* dbus: when a unit failed to load (i.e. is in UNIT_ERROR state), we
* add a pam module that passes the hdd passphrase into the PAM stack and then expires it, for usage by gdm auto-login.
* maybe add a generator that looks for "systemd.run=" on the kernel cmdline for container usercases...
* timedatctl, localectl: possibly make some commands work without the daemon, for chroot situations...
* timedatectl: print a nicer message when enabling ntp fails because ntpd/chrony are not installed
* systemctl delete x.snapshot leaves no trace in logs (at least at default level).
* systemd-inhibit: make taking delay locks useful: support sending SIGINT or SIGTERM on PrepareForSleep()
* journal-or-kmsg is currently broken? See reverted commit 4a01181e460686d8b4a543b1dfa7f77c9e3c5ab8.
* remove any syslog support from log.c -- we probably cannot do this before split-off udev is gone for good
* think about window-manager-run-as-user-service problem: exit 0 → activate shutdown.target; exit != 0 → restart service
* timedate: have global on/off switches for auto-time (NTP), and auto-timezone that connman can subscribe to.
- change bootctl to be backed by systemd-bootd to control temporary and persistent default boot goal plus efi variables
* fstab: add new mount option x-systemd-after=/foobar/waldo to allow manual dependencies to other mount points
* print a nicer explanation if people use variable/specifier expansion in ExecStart= for the first word
* mount: turn dependency information from /proc/self/mountinfo into dependency information between systemd units.
- 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
- we should probably handle SIGTERM/SIGINT to not leave dot files around, just in case
- 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.
* exec: when deinitializating a tty device fix the perms and group, too, not only when initializing. Set access mode/gid to 0620/tty.
- 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?
- check if we can make journalctl by default use --follow mode inside of less if called without args?
- journal: add a setgid "systemd-journal" utility to invoke from libsystemd-journal, which passes fds via STDOUT and does PK access
- journactl: support negative filtering, i.e. FOOBAR!="waldo",
- journal: send out marker messages every now and then, and immediately sync with fdatasync() afterwards, in order to have hourly guaranteed syncs.
- 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: sanely deal with entries which are larger than the individual file size, but where the components would fit
- tmpfiles: when applying ownership to /run/log/journal, also do this for the journal fails contained in it
- man: clarify that time-sync.target is not only sysv compat but also useful otherwise. Same for similar targets
- add a man page containing packaging guidelines and recommending usage of things like Documentation=, PrivateTmp=, PrivateNetwork= and ReadOnlyDirectories=/etc /usr.
- document systemd-journal-flush.service properly
- documentation: recommend to connect the timer units of a service to the service via Also= in [Install]
- man: extend runlevel(8) to mention that runlevels suck, and are dead. Maybe add runlevel(7) with a note about that too
- 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: improve the success messages (i.e. more human readable, less shell-like)
- systemctl enable: fail if target to alias into does not exist? maybe show how many units are enabled afterwards?
- systemctl list-unit-files should list generated files (and probably with a new state "generated" for them, or so)
* introduce ntp.service (or suchlike) as symlink that is used to arbitrate between various NTP implementations
* deal with sendmail/postfix exclusivity
- when parsing calendar timestamps support the UTC timezone (even if we will not support arbitrary timezone specs, support UTC itself certainly makes sense), also support syntaxes such as +0200
- DST/timezone changes && ntp is active && RTC-in-localtime (never do it without ntp)
logs-show.c. Alternatively: use libelfutil, which seems to be the
* If we show an error about a unit (such as not showing up) and it has no Description string, then show a description string generated form the reverse of unit_name_mangle().
* clean up date formatting and parsing so that all absolute/relative timestamps we format can also be parsed
* on shutdown: move utmp, wall, audit logic all into PID 1 (or logind?), get rid of systemd-update-utmp-runlevel
- instructions shipped by packages and stored in /usr/lib/
* hostnamed: before returning information from /etc/machine-info.conf check the modification data and reread. Similar for localed, ...
* currently x-systemd.timeout is lost in the initrd, since crypttab is copied into dracut, but fstab is not
- nspawn: make it work for dwalsh and shared /usr containers -- tmpfs mounts as command line parameters
- refuses to boot containers without /etc/machine-id (OK?), and with empty /etc/machine-id (not OK).
- generate predictable mac addresses for the netdev we create (host0), maybe based on guest's machine
- support rd.luks.allow-discards= kernel cmdline params in cryptsetup generator
* after deserializing sockets in socket.c we should reapply sockopts and things
* come up with a nice way to write queue/read_ahead_kb for a block device without interfering with readahead
* move PID 1 segfaults to /var/lib/systemd/coredump?
* create /sbin/init symlinks from the build system
* properly handle loop back mounts via fstab, especially regards to fsck/passno
* initialize the hostname from the fs label of /, if /etc/hostname does not exist?
* when breaking cycles drop sysv services first, then services from /run, then from /etc, then from /usr
* ExecOnFailure=/usr/bin/foo
- remove src/udev/udev-builtin-firmware.c (CONFIG_FW_LOADER_USER_HELPER=n)
- add trigger --subsystem-match=usb/usb_device device
* when a service has the same env var set twice we actually store it twice and return that in systemctl show -p... We should only show the last setting
* add option to sockets to avoid activation. Instead just drop packets/connections, see http://cyberelk.net/tim/2012/02/15/portreserve-systemd-solution/
* save coredump in Windows/Mozilla minidump format
* support crash reporting operation modes (https://live.gnome.org/GnomeOS/Design/Whiteboards/ProblemReporting)
* default to actual 32-bit PIDs, via /proc/sys/kernel/pid_max
* when a bus name of a service disappears from the bus make sure to queue further activation requests
* support sd_notify() style notification when reload begins (RELOADING=1), reload is finished (READY=1), and add ReloadSignal= then to use in combination
* support sd_notify() style notification when shutting down, to make auto-exit bus services work (STOPPING=1)
- readahead: make use of EXT4_IOC_MOVE_EXT, as used by http://e4rat.sourceforge.net/
* add support for /bin/mount -s
- init=/bin/sh vs. "emergency" mode, vs. "rescue" mode, vs. "multi-user" mode, vs. "graphical" mode, and the debug shell
- hooking a script into various stages of shutdown/rearly booot
* support systemd.mask= on the kernel command line.
- add documentation to systemd.daemon
- inbuilt piping support (essentially degenerate async)? see loopback-setup.c and other places
- add proper initrd support (in particular generate .network/.link files based on /proc/cmdline)
- patch kernel to support module alias for tunnel device (ipip/sit/gre),
- add tun/tap netdev support
- teach dbus to activate all services it finds in /etc/systemd/services/org-*.service
* dbus upstream still refers to dbus.target and should not
* /usr/bin/service should actually show the new command line
* fedora: suggest auto-restart on failure, but not on success and not on coredump. also, ask people to think about changing the start limit logic. Also point people to RestartPreventExitStatus=, SuccessExitStatus=
* fedora: F20: go timer units all the way, leave cron.daily for cron
* fedora: update policy to declare access mode and ownership of unit files to root:root 0644, and add an rpmlint check for it
* set_put(), hashmap_put() return values check. i.e. == 0 does not free()!
