basic/terminal-util: introduce SYSTEMD_COLORS environment variable ... to determine if color output should be enabled. If the variable is not set, fall back to using on_tty(). Also, rewrite existing code to use colors_enabled() where appropriate.

man: fix typos

core: Add machine-id setting Allow for overriding all other machine-ids which may be present on the system using a kernel command line systemd.machine_id or --machine-id= option. This is especially useful for network booted systems where the machine-id needs to be static, or for containers where a specific machine-id is wanted.

Remove snapshot unit type Snapshots were never useful or used for anything. Many systemd developers that I spoke to at systemd.conf2015, didn't even know they existed, so it is fairly safe to assume that this type can be deleted without harm. The fundamental problem with snapshots is that the state of the system is dynamic, devices come and go, users log in and out, timers fire... and restoring all units to some state from the past would "undo" those changes, which isn't really possible. Tested by creating a snapshot, running the new binary, and checking that the transition did not cause errors, and the snapshot is gone, and snapshots cannot be created anymore. New systemctl says: Unknown operation snapshot. Old systemctl says: Failed to create snapshot: Support for snapshots has been removed. IgnoreOnSnaphost settings are warned about and ignored: Support for option IgnoreOnSnapshot= has been removed and it is ignored http://lists.freedesktop.org/archives/systemd-devel/2015-November/034872.html

doc: correct orthography, word forms and missing/extraneous words

doc: correct punctuation and improve typography in documentation

core: change how crash_shell and crash_reboot interact Instead of freezing in PID1 and letting the forked child freeze or reboot when exec("/bin/sh") fails, just wait for the child's exit and then do the freeze_or_reboot in PID1 as usual. This means that when both crash_shell and crash_reboot are enabled, the system will reboot after the shell exits.

core: add support for naming file descriptors passed using socket activation This adds support for naming file descriptors passed using socket activation. The names are passed in a new $LISTEN_FDNAMES= environment variable, that matches the existign $LISTEN_FDS= one and contains a colon-separated list of names. This also adds support for naming fds submitted to the per-service fd store using FDNAME= in the sd_notify() message. This also adds a new FileDescriptorName= setting for socket unit files to set the name for fds created by socket units. This also adds a new call sd_listen_fds_with_names(), that is similar to sd_listen_fds(), but also returns the names of the fds. systemd-activate gained the new --fdname= switch to specify a name for testing socket activation. This is based on #1247 by Maciej Wereski. Fixes #1247.

core: rework crash handling This introduces a new systemd.crash_reboot=1 kernel command line option that triggers a reboot after crashing. This also cleans up crash VT handling. Specifically, it cleans up the configuration setting, to be between 1..63 or a boolean. This is to replace the previous logic where "-1" meant disabled. We continue to accept that setting, but only document the boolean syntax instead. This also brings the documentation of the default settings in sync with what actually happens. The CrashChVT= configuration file setting is renamed to CrashChangeVT=, following our usual logic of not abbreviating unnecessarily. The old setting stays support for compat reasons. Fixes #1300

man: add systemd-cgls as tool that shows the cgroup hierarchy

man: revert dynamic paths for split-usr setups This did not really work out as we had hoped. Trying to do this upstream introduced several problems that probably makes it better suited as a downstream patch after all. At any rate, it is not releaseable in the current state, so we at least need to revert this before the release. * by adjusting the path to binaries, but not do the same thing to the search path we end up with inconsistent man-pages. Adjusting the search path too would be quite messy, and it is not at all obvious that this is worth the effort, but at any rate it would have to be done before we could ship this. * this means that distributed man-pages does not make sense as they depend on config options, and for better or worse we are still distributing man pages, so that is something that definitely needs sorting out before we could ship with this patch. * we have long held that split-usr is only minimally supported in order to boot, and something we hope will eventually go away. So before we start adding even more magic/effort in order to make this work nicely, we should probably question if it makes sense at all.

man: generate configured paths in manpages In particular, use /lib/systemd instead of /usr/lib/systemd in distributions like Debian which still have not adopted a /usr merge setup. Use XML entities from man/custom-entities.ent to replace configured paths while doing XSLT processing of the original XML files. There was precedent of some files (such as systemd.generator.xml) which were already using this approach. This addresses most of the (manual) fixes from this patch: http://anonscm.debian.org/cgit/pkg-systemd/systemd.git/tree/debian/patches/Fix-paths-in-man-pages.patch?h=experimental-220 The idea of using generic XML entities was presented here: http://lists.freedesktop.org/archives/systemd-devel/2015-May/032240.html This patch solves almost all the issues, with the exception of: - Path to /bin/mount and /bin/umount. - Generic statements about preference of /lib over /etc. These will be handled separately by follow up patches. Tested: - With default configure settings, ran "make install" to two separate directories and compared the output to confirm they matched exactly. - Used a set of configure flags including $CONFFLAGS from Debian: http://anonscm.debian.org/cgit/pkg-systemd/systemd.git/tree/debian/rules Installed the tree and confirmed the paths use /lib/systemd instead of /usr/lib/systemd and that no other unexpected differences exist. - Confirmed that `make distcheck` still passes.

shutdownd: kill the old implementation Not that all functionality has been ported over to logind, the old implementation can be removed. There goes one of the oldest parts of the systemd code base.

man: add a mapping for external manpages It is annoying when we have dead links on fd.o. Add project='man-pages|die-net|archlinux' to <citerefentry>-ies. In generated html, add external links to http://man7.org/linux/man-pages/man, http://linux.die.net/man/, https://www.archlinux.org/. By default, pages in sections 2 and 4 go to man7, since Michael Kerrisk is the autorative source on kernel related stuff. The rest of links goes to linux.die.net, because they have the manpages. Except for the pacman stuff, since it seems to be only available from archlinux.org. Poor gummiboot gets no link, because gummitboot(8) ain't to be found on the net. According to common wisdom, that would mean that it does not exist. But I have seen Kay using it, so I know it does, and deserves to be found. Can somebody be nice and put it up somewhere?

man: xinclude --help/--version/--no-pager

doc: update punctuation Resolve spotted issues related to missing or extraneous commas, dashes.

manager: add systemd.show_status=auto mode When set to auto, status will shown when the first ephemeral message is shown (a job has been running for five seconds). Then until the boot or shutdown ends, status messages will be shown. No indication about the switch is done: I think it should be clear for the user that first the cylon eye and the ephemeral messages appear, and afterwards messages are displayed. The initial arming of the event source was still wrong, but now should really be fixed.

rework systemd's own process environment handling/passing Stop importing non-sensical kernel-exported variables. All parameters in the kernel command line are exported to the initial environment of PID1, but suppressed if they are recognized by kernel built-in code. The EFI booted kernel will add further kernel-internal things which do not belong into userspace. The passed original environ data of the process is not touched and preserved across re-execution, to allow external reading of /proc/self/environ for process properties like container*=.

man: use <constant> for various constants which look ugly with quotes

core: read "debug" from kernel commandline and set log level

systemd-sleep: add support for freeze and standby A new config file /etc/systemd/sleep.conf is added. It is parsed by systemd-sleep and logind. The strings written to /sys/power/disk and /sys/power/state can be configured. This allows people to use different modes of suspend on systems with broken or special hardware. Configuration is shared between systemd-sleep and logind to enable logind to answer the question "can the system be put to sleep" as correctly as possible without actually invoking the action. If the user configured systemd-sleep to only use 'freeze', but current kernel does not support it, logind will properly report that the system cannot be put to sleep. https://bugs.freedesktop.org/show_bug.cgi?id=57793 https://git.kernel.org/?p=linux/kernel/git/torvalds/linux.git;a=commit;h=7e73c5ae6e7991a6c01f6d096ff8afaef4458c36 http://lists.freedesktop.org/archives/systemd-devel/2013-February/009238.html SYSTEM_CONFIG_FILE and USER_CONFIG_FILE defines were removed since they were used in only a few places and with the addition of /etc/systemd/sleep.conf it becomes easier to just append the name of each file to the dir name.

Revert "man/systemd.xml: change the signal names to kill systemd" This reverts commit 432c30d25fc2a7b4939d5ea6c29708e1323a2b9c. Suggestion was to fix bash instead. :-/

man/systemd.xml: change the signal names to kill systemd Using the signal name to put systemd in debug mode with bash results in: $ kill -s SIGRTMIN+22 1 bash: kill: SIGRTMIN+22: invalid signal specification whereas this works: $ kill -s SIGRTMAX-8 1 /usr/bin/kill understands both signal names, so just change them to the bash names.

man: rename systemd.conf to systemd-system.conf Alias as systemd-user.conf is also provided. This should help users running systemd in session mode. https://bugzilla.redhat.com/show_bug.cgi?id=690868

man: describe unit load path in systemd.unit(5) In other cases where multiple directories are searched for unit files, the list of directories is described in the man page describing the format. I think this makes sense too in case of systemd directories, since the systemd(1) manpage already has an overview of many different topics.

man: extend systemd.directives(7) to all manual pages New sections are added: PAM options, crypttab options, commandline options, miscellaneous. The last category will be used for all untagged <varname> elements. Commandline options sections is meant to be a developer tool: when adding an option it is sometimes useful to be able to check if similarly named options exist elsewhere.

man: add links to directive index to see-alsos systemd.directives(5) is renamed to systemd.directives(7). Section 7 is "Miscellaneous".

make-directive-index: link to systemd options

man: typo fixes https://bugs.freedesktop.org/show_bug.cgi?id=55890 Fixed typos, serial comma, and removed "either" as there were more than two options. Also did an extra rename of "system-shutdown" to "systemd-shutdown" that was forgotten in commit 8bd3b8620c80d0f2383f2fb04315411fc8077ca1

manager: connect SIGRTMIN+24 to terminating --user instances

Reword sentences that contain psuedo-English "resp." As you likely know, Arch Linux is in the process of moving to systemd. So I was reading through the various systemd docs and quickly became baffled by this new abbreviation "resp.", which I've never seen before in my English-mother-tongue life. Some quick Googling turned up a reference: <http://www.transblawg.eu/index.php?/archives/870-Resp.-and-other-non-existent-English-wordsNicht-existente-englische-Woerter.html> I guess it's a literal translation of the German "Beziehungsweise", but English doesn't work the same way. The word "respectively" is used exclusively to provide an ordering connection between two lists. E.g. "the prefixes k, M, and G refer to kilo-, mega-, and giga-, respectively." It is also never abbreviated to "resp." So the sentence "Sets the default output resp. error output for all services and sockets" makes no sense to a natural English speaker. This patch removes all instances of "resp." in the man pages and replaces them with sentences which are much more clear and, hopefully, grammatically valid. In almost all instances, it was simply replacing "resp." with "or," which the original author (Lennart?) could probably just do in the future. The only other instances of "resp." are in the src/ subtree, which I don't feel privileged to correct. Signed-off-by: Andrew Eikum <aeikum@codeweavers.com>

man: mention journalctl in the systemd man page

systemd: add --version option systemd --version mirrors systemctl --version: $ ./systemd --version systemd 186 other +PAM +LIBWRAP +AUDIT +SELINUX +IMA +SYSVINIT -LIBCRYPTSETUP This information can be retrieved by other means (systemctl, etc.), but it's easier for a newbie if 'systemd --version' says something useful. And 'systemd --help' is already there, so let's complement that with '--version'.

core: remove sysv_console option This option never made much sense. It was originally intended to make sure that the usual startup output of sysv scripts goes to the terminal. However, since SysV scripts started from a terminal would not output to that terminal, but rather /dev/console this effect was more often than not actually taking place. Nowadays systemd has much nicer boot time status output than SysV which makes the sysv output redundant. Finally, all output of services goes to the journal anyway, and is not lost. Hence, let's drop this option, and simplify things a bit.

man: document all kernel command line options we understand

relicense to LGPLv2.1 (with exceptions) We finally got the OK from all contributors with non-trivial commits to relicense systemd from GPL2+ to LGPL2.1+. Some udev bits continue to be GPL2+ for now, but we are looking into relicensing them too, to allow free copy/paste of all code within systemd. The bits that used to be MIT continue to be MIT. The big benefit of the relicensing is that closed source code may now link against libsystemd-login.so and friends.
