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.

systemctl: allow multiple arguments to --type This mirrors --property, and is generally useful. New functionality is used in bash completion. In case of zsh completion, new functionality is less useful because of caching. Nevertheless, zsh completion for restart is made to behave more-or-less the same as bash completion. At least sockets can be restarted.

<para>Note that unit glob patterns expand to names of units currently in memory. Units which are
not active and are not in a failed state usually are not in memory, and will not be matched by
any pattern. In addition, in case of instantiated units, systemd is often unaware of the instance
name until the instance has been started. Therefore, using glob patterns with
<command>start</command> has limited usefulness. Also, secondary alias names of units are not
considered.</para>

systemctl: add support for --wait to is-system-running This makes it possible to wait until boot is finished without having to poll for this command repeatedly, instead using the syntax: $ systemctl is-system-running --wait Waiting is implemented by waiting for the StartupFinished signal to be posted on the bus. Register the matcher before checking for the property to avoid race conditions. Tested by artificially delaying startup with a oneshot service and calling this command, checked that it emitted `running` and exited with a 0 return code as soon as the delay service completed startup. Also tested that booting to degraded state unblocks the command. Inserted a delay between getting the property and waiting for the signal and confirmed this seems to work free of race conditions. Updated the --help text (under --wait) and the man page to document the new feature.

<title>System Commands</title>
core: allow 'SetUnitProperties()' to run on inactive units too 'set-property' has been primarly designed to change some properties of *active* units. However it can easily work on inactive units as well. In that case changes are only saved in a drop-in for futur uses and changes will be effective when unit will be started. Actually it already works on inactive units but that was not documented and not fully supported. Indeed the inactive units had to be known by the manager otherwise it was reported as not loaded: $ systemctl status my-test.service * my-test.service - My Testing Unit Loaded: loaded (/etc/systemd/system/my-test.service; static; vendor preset: disabled) Drop-In: /etc/systemd/system/my-test.service.d Active: inactive (dead) $ systemctl set-property my-test.service MemoryLimit=1000000 Failed to set unit properties on my-test.service: Unit my-test.service is not loaded. [ Note: that the unit load state reported by the 'status' command might be confusing since it claimed the unit as loaded but 'set-property' reported the contrary. ] One can possibily workaround this by making the unit a dependency of another active unit so the manager will keep it around: $ systemctl add-wants multi-user.target my-test.service Created symlink from /etc/systemd/system/multi-user.target.wants/my-test.service to /etc/systemd/system/my-test.service. $ systemctl set-property my-test.service MemoryLimit=1000000 $ systemctl status my-test.service * my-test.service - My Testing Unit Loaded: loaded (/etc/systemd/system/my-test.service; enabled; vendor preset: disabled) Drop-In: /etc/systemd/system/my-test.service.d `-50-MemoryLimit.conf Active: inactive (dead) This patch simply forces 'SetUnitProperties()' to load the unit if it's not already the case. It also documents the fact that 'set-property' can be used on inactive units.

intended for usage in initial RAM disks ("initrd"), and will transition from the initrd's system manager
process (a.k.a. "init" process) to the main system manager process which is loaded from the actual host
volume. This call takes two arguments: the directory that is to become the new root directory, and the path
to the new system manager binary below it to execute as PID 1. If the latter is omitted or the empty
string, a systemd binary will automatically be searched for and used as init. If the system manager path is
omitted, equal to the empty string or identical to the path to the systemd binary, the state of the
initrd's system manager process is passed to the main system manager, which allows later introspection of
the state of the services involved in the initrd boot phase.</para>

systemctl,pid1: do not warn about missing install info with "preset" When "preset" was executed for a unit without install info, we'd warn similarly as for "enable" and "disable". But "preset" is usually called for all units, because the preset files are provided by the distribution, and the units are under control of individual programs, and it's reasonable to call "preset" for all units rather then try to do it only for the ones that can be installed. We also don't warn about missing info for "preset-all". Thus it seems reasonable to silently ignore units w/o install info when presetting. (In addition, when more than one unit was specified, we'd issue the warning only if none of them had install info. But this is probably something to fix for enable/disable too.)

<para>Unit commands listed above take either a single unit name (designated as <replaceable>UNIT</replaceable>),
or multiple unit specifications (designated as <replaceable>PATTERN</replaceable>…). In the first case, the
unit name with or without a suffix must be given. If the suffix is not specified (unit name is "abbreviated"),
systemctl will append a suitable suffix, <literal>.service</literal> by default, and a type-specific suffix in
case of commands which operate only on specific unit types. For example,
<programlisting># systemctl start sshd</programlisting> and
<programlisting># systemctl start sshd.service</programlisting>
are equivalent, as are
<programlisting># systemctl isolate default</programlisting>
and
<programlisting># systemctl isolate default.target</programlisting>
Note that (absolute) paths to device nodes are automatically converted to device unit names, and other (absolute)
paths to mount unit names.
<programlisting># systemctl status /dev/sda
# systemctl status /home</programlisting>
are equivalent to:
<programlisting># systemctl status dev-sda.device
# systemctl status home.mount</programlisting>
In the second case, shell-style globs will be matched against the primary names of all units currently in memory;
literal unit names, with or without a suffix, will be treated as in the first case. This means that literal unit
names always refer to exactly one unit, but globs may match zero units and this is not considered an
error.</para>

units currently in memory, and patterns which do not match anything
are silently skipped. For example:
<programlisting># systemctl stop sshd@*.service</programlisting>
will stop all <filename>sshd@.service</filename> instances. Note that alias names of units, and units that aren't

systemctl: add support for --wait to is-system-running This makes it possible to wait until boot is finished without having to poll for this command repeatedly, instead using the syntax: $ systemctl is-system-running --wait Waiting is implemented by waiting for the StartupFinished signal to be posted on the bus. Register the matcher before checking for the property to avoid race conditions. Tested by artificially delaying startup with a oneshot service and calling this command, checked that it emitted `running` and exited with a 0 return code as soon as the delay service completed startup. Also tested that booting to degraded state unblocks the command. Inserted a delay between getting the property and waiting for the signal and confirmed this seems to work free of race conditions. Updated the --help text (under --wait) and the man page to document the new feature.

process, the control process or all processes of the
unit. The main process of the unit is the one that defines
the life-time of it. A control process of a unit is one that
is invoked by the manager to induce state changes of it. For
example, all processes started due to the
<varname>ExecStartPre=</varname>,
<varname>ExecStop=</varname> or
<varname>ExecReload=</varname> settings of service units are
control processes. Note that there is only one control
process per unit at a time, as only one state change is
executed at a time. For services of type
<varname>Type=forking</varname>, the initial process started
by the manager for <varname>ExecStart=</varname> is a
control process, while the process ultimately forked off by
that one is then considered the main process of the unit (if
it can be determined). This is different for service units
of other types, where the process forked off by the manager
for <varname>ExecStart=</varname> is always the main process
itself. A service unit consists of zero or one main process,
zero or one control process plus any number of additional
processes. Not all unit types manage processes of these
types however. For example, for mount units, control processes
are defined (which are the invocations of
<filename>&MOUNT_PATH;</filename> and

is defined. If omitted, defaults to

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?
