+
+ <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>Enable one or more units or unit instances. This will create a set of symlinks, as encoded in the
+ <literal>[Install]</literal> sections of the indicated unit files. After the symlinks have been created,
+ the system manager configuration is reloaded (in a way equivalent to <command>daemon-reload</command>), in

+ the form <filename>foo@bar.service</filename>), symlinks named the same as instances are created in the
+ unit configuration diectory, however they point to the single template unit file they are instantiated
+ from.</para>
+
+ <para>This command expects either valid unit names (in which case various unit file directories are
+ automatically searched for unit files with appropriate names), or absolute paths to unit files (in which
+ case these files are read directly). If a specified unit file is located outside of the usual unit file
+ directories, an additional symlink is created, linking it into the unit configuration path, thus ensuring

+
+ <para>Note that this operation creates only the symlinks suggested in the <literal>[Install]</literal>

+ below this directory. This is particularly useful to create configurations that deviate from the suggested

+ <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>

+ <title>Description</title>
+
+ <para>Preset files may be used to encode policy which units shall
+ be enabled by default and which ones shall be disabled. They are
+ read by <command>systemctl preset</command> (for more information
+ see
+ <citerefentry><refentrytitle>systemctl</refentrytitle><manvolnum>1</manvolnum></citerefentry>)
+ which uses this information to enable or disable a unit according
+ to preset policy. <command>systemctl preset</command> is used by
+ the post install scriptlets of RPM packages (or other OS package
+ formats), to enable/disable specific units by default on package
+ installation, enforcing distribution, spin or administrator preset
+ policy. This allows choosing a certain set of units to be
+ enabled/disabled even before installing the actual package.</para>
+
+ <para>For more information on the preset logic please have a look
+ at the <ulink
+ url="http://freedesktop.org/wiki/Software/systemd/Preset">Presets</ulink>
+ document.</para>
+
+ <para>It is not recommended to ship preset files within the
+ respective software packages implementing the units, but rather
+ centralize them in a distribution or spin default policy, which
+ can be amended by administrator policy.</para>
+
+ <para>If no preset files exist, <command>systemctl
+ preset</command> will enable all units that are installed by
+ default. If this is not desired and all units shall rather be
+ disabled, it is necessary to ship a preset file with a single,
+ catchall "<filename>disable *</filename>" line. (See example 1,
+ below.)</para>
+ </refsect1>
+
+ <refsect1>
+ <title>Preset File Format</title>
+
+ <para>The preset files contain a list of directives consisting of
+ either the word <literal>enable</literal> or
+ <literal>disable</literal> followed by a space and a unit name
+ (possibly with shell style wildcards), separated by newlines.
+ Empty lines and lines whose first non-whitespace character is # or
+ ; are ignored.</para>
+
+ <para>Two different directives are understood:
+ <literal>enable</literal> may be used to enable units by default,
+ <literal>disable</literal> to disable units by default.</para>
+
+ <para>If multiple lines apply to a unit name, the first matching
+ one takes precedence over all others.</para>
+
+ <para>Each preset file shall be named in the style of
+ <filename>&lt;priority&gt;-&lt;policy-name&gt;.preset</filename>. Files
+ in <filename>/etc/</filename> override files with the same name in
+ <filename>/usr/lib/</filename> and <filename>/run/</filename>.
+ Files in <filename>/run/</filename> override files with the same
+ name in <filename>/usr/lib/</filename>. Packages should install
+ their preset files in <filename>/usr/lib/</filename>. Files in
+ <filename>/etc/</filename> are reserved for the local
+ administrator, who may use this logic to override the preset files
+ installed by vendor packages. All preset files are sorted by their
+ filename in lexicographic order, regardless of which of the
+ directories they reside in. If multiple files specify the same
+ unit name, the entry in the file with the lexicographically
+ earliest name will be applied. It is recommended to prefix all
+ filenames with a two-digit number and a dash, to simplify the
+ ordering of the files.</para>
+
+ <para>If the administrator wants to disable a preset file supplied
+ by the vendor, the recommended way is to place a symlink to
+ <filename>/dev/null</filename> in
+ <filename>/etc/systemd/system-preset/</filename> bearing the same
+ filename.</para>
+ </refsect1>
+
+ <refsect1>
+ <title>Example</title>
+
+ <example>
+ <title>Default off example <filename>/usr/lib/systemd/system-preset/99-default.preset</filename>:</title>
+
+ <programlisting>disable *</programlisting>
+ </example>
+
+ <para>This disables all units. Due to the filename prefix
+ <literal>99-</literal>, it will be read last and hence can easily
+ be overridden by spin or administrator preset policy or
+ suchlike.</para>
+
+ <example>
+ <title>A GNOME spin example <filename>/usr/lib/systemd/system-preset/50-gnome.preset</filename>:</title>
+
+ <programlisting>enable gdm.service
+enable colord.service
+enable accounts-daemon.service
+enable avahi-daemon.*</programlisting>
+
+ </example>
+
+ <para>This enables the three mentioned units, plus all
+ <filename>avahi-daemon</filename> regardless of which unit type. A
+ file like this could be useful for inclusion in a GNOME spin of a
+ distribution. It will ensure that the units necessary for GNOME
+ are properly enabled as they are installed. It leaves all other
+ units untouched, and subject to other (later) preset files, for
+ example like the one from the first example above.</para>
+
+ <example>
+ <title>Administrator policy <filename>/etc/systemd/system-preset/00-lennart.preset</filename>:</title>
+
+ <programlisting>enable httpd.service
+enable sshd.service
+enable postfix.service
+disable *</programlisting>
+ </example>
+
+ <para>This enables three specific services and disables all
+ others. This is useful for administrators to specifically select
+ the units to enable, and disable all others. Due to the filename
+ prefix <literal>00-</literal> it will be read early and hence
+ overrides all other preset policy files.</para>
