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><priority>-<program>.conf</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 alphabetical - order, regardless in which of the directories they - reside, to guarantee that a specific preset file takes - precedence over another file with an alphabetically - earlier name, if both files contain lines that apply - to the same unit names. It is recommended to prefix - all file names with two-digit number, to simplify - ordering.</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 file name.</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 file name - 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 file name prefix - <literal>00-</literal> it will be read early and hence - overrides all other preset policy files.</para> - </refsect1> - - <refsect1> - <title>See Also</title> - <para> - <citerefentry><refentrytitle>systemd</refentrytitle><manvolnum>1</manvolnum></citerefentry>, - <citerefentry><refentrytitle>systemctl</refentrytitle><manvolnum>1</manvolnum></citerefentry>, - <citerefentry><refentrytitle>systemd-delta</refentrytitle><manvolnum>1</manvolnum></citerefentry> - </para> - </refsect1> - -</refentry> |
