+ <title>Overview</title>
+
+ <para>"Runlevels" are an obsolete way to start and stop groups of
+ services used in SysV init. systemd provides a compatibility layer
+ that maps runlevels to targets, and associated binaries like
+ <command>runlevel</command>. Nevertheless, only one runlevel can
+ be "active" at a given time, while systemd can activate multiple
+ targets concurrently, so the mapping to runlevels is confusing
+ and only approximate. Runlevels should not be used in new code,
+ and are mostly useful as a shorthand way to refer the matching
+ systemd targets in kernel boot parameters.</para>

+
+ <para>If <literal>replace</literal> (the default) is

+
+ <para>If <literal>replace-irreversibly</literal> is specified,

+ jobs can still be cancelled using the <command>cancel</command>
+ command.</para>
+
+ <para><literal>isolate</literal> is only valid for start
+ operations and causes all other units to be stopped when the

+
+ <para><literal>flush</literal> will cause all queued jobs to
+ be canceled when the new job is enqueued.</para>
+
+ <para>If <literal>ignore-dependencies</literal> is specified,
+ then all unit dependencies are ignored for this new job and
+ the operation is executed immediately. If passed, no required
+ units of the unit passed will be pulled in, and no ordering
+ dependencies will be honored. This is mostly a debugging and
+ rescue tool for the administrator and should not be used by
+ applications.</para>
+
+ <para><literal>ignore-requirements</literal> is similar to
+ <literal>ignore-dependencies</literal>, but only causes the

+ <command>systemctl</command> will query the user on the
+ terminal for the necessary secrets. Use this option to

+
+ <varlistentry>
+ <term><option>--kill-who=</option></term>
+
+ <listitem>
+ <para>When used with <command>kill</command>, choose which
+ processes to send a signal to. Must be one of
+ <option>main</option>, <option>control</option> or
+ <option>all</option> to select whether to kill only the main
+ 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
+ <filename>&UMOUNT_PATH;</filename>), but no main process
+ is defined. If omitted, defaults to

+ <para>Revert one or more unit files to their vendor versions. This command removes drop-in configuration
+ files that modify the specified units, as well as any user-configured unit file that overrides a matching
+ vendor supplied unit file. Specifically, for a unit <literal>foo.service</literal> the matching directories
+ <literal>foo.service.d/</literal> with all their contained files are removed, both below the persistent and
+ runtime configuration directories (i.e. below <filename>/etc/systemd/system</filename> and
+ <filename>/run/systemd/system</filename>); if the unit file has a vendor-supplied version (i.e. a unit file
+ located below <filename>/usr</filename>) any matching peristent or runtime unit file that overrides it is
+ removed, too. Note that if a unit file has no vendor-supplied version (i.e. is only defined below
+ <filename>/etc/systemd/system</filename> or <filename>/run/systemd/system</filename>, but not in a unit
+ file stored below <filename>/usr</filename>), then it is not removed. Also, if a unit is masked, it is

+ <title>Parameter Syntax</title>
+
+ <para>Unit commands listed above take either a single unit name (designated as <replaceable>NAME</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 currently loaded units;
+ 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>
+
+ <para>Glob patterns use
+ <citerefentry project='man-pages'><refentrytitle>fnmatch</refentrytitle><manvolnum>3</manvolnum></citerefentry>,
+ so normal shell-style globbing rules are used, and
+ <literal>*</literal>, <literal>?</literal>,
+ <literal>[]</literal> may be used. See
+ <citerefentry project='man-pages'><refentrytitle>glob</refentrytitle><manvolnum>7</manvolnum></citerefentry>
+ for more details. The patterns are matched against the primary names of
+ currently loaded units, 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
+ loaded are not considered for glob expansion.
+ </para>
+
+ <para>For unit file commands, the specified <replaceable>NAME</replaceable> should be the name of the unit file
+ (possibly abbreviated, see above), or the absolute path to the unit file:
+ <programlisting># systemctl enable foo.service</programlisting>
+ or
+ <programlisting># systemctl link /path/to/foo.service</programlisting>
