<title>Description</title>
<para><command>systemd-install</command> enables or
disables systemd units, or checks whether they are
enabled.</para>
<para>This command is useful to apply or undo the
installation instructions encoded in the <literal>[Install]</literal>
section of unit files. See
<citerefentry><refentrytitle>systemd.unit</refentrytitle><manvolnum>5</manvolnum></citerefentry>
for more information.</para>
<para>Enabling units (as with <command>systemd-install
enable</command>) should not be confused with
activating units (as with <command>systemctl
start</command>). The former simply installs the unit
files in the configuration tree, but does not start
them. The latter equals starting them, but does not
necessarily require them to be enabled.</para>
</refsect1>
<refsect1>
<title>Options</title>
<para>The following options are understood:</para>
<variablelist>
<varlistentry>
<term><option>--help</option></term>
<listitem><para>Prints a short help
text and exits.</para></listitem>
</varlistentry>
<varlistentry>
<term><option>--force</option></term>
<listitem><para>Enable/disable a
service even if it conflicts
with/contradicts another service. This
might have the effect of disabling
another service that was
enabled.</para></listitem>

<listitem><para>Enable/disable a

<varlistentry>
<term><option>--start[=MODE]</option></term>
<listitem><para>After
enabling/disabling stop/restart the
unit and reload manager
configuration. Optionally, takes one
of <option>no</option>,
<option>minimal</option>,
<option>maybe</option> or
<option>yes</option>. If
<option>no</option> is passed the
manager will not reload its
configuration and no service will be
started or stopped after
enabling/disabling of the unit
files. If <option>minimal</option> is
passed and a unit is being enabled it
will also be restarted should it
already be running. If a unit is being
disabled it will be stopped should it
be running. In either case the
daemon configuration is
reloaded. <option>maybe</option> is
similar to this, but the unit will
also be started if it is being enabled
and any of the units listed in
<varname>WantedBy=</varname> in the
<literal>[Install]</literal> section
of the unit file is already
activated. Finally
<option>yes</option> starts the unit
unconditionally after enabling. This
setting defaults to
<option>no</option>. If the mode value
is omitted defaults to
<option>maybe</option>. This option
has no effect when
<option>--global</option> or
<command>test</command> is
used.</para></listitem>
