<title>Description</title>
|
|
|
|
<para><command>systemd-install</command> enables or
|
|
disables systemd units, or checks whether they are
|
|
enabled, according to the installation suggestions
|
|
included in the unit files.</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>
|
|
|
|
<para>Note that while
|
|
<command>systemd-install</command> is the recommended
|
|
tool to create or remove symlinks in the systemd
|
|
configuration directory the administrator can also
|
|
create links there manually, which is particularly
|
|
useful to use configurations that deviate from the
|
|
installation suggestions included in the unit
|
|
files.</para>

started or stopped after

it will be stopped should it be

similar to this, but the unit will
