<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>
