конфигурация агрегата (Unit configuration)
[INSTALL] SECTION OPTIONS
Unit files may include an [Install] section, which carries
installation information for the unit. This section is not
interpreted by systemd(1) during runtime; it is used by the
enable and disable commands of the systemctl(1) tool during
installation of a unit.
Alias=
A space-separated list of additional names this unit shall be
installed under. The names listed here must have the same
suffix (i.e. type) as the unit filename. This option may be
specified more than once, in which case all listed names are
used. At installation time, systemctl enable will create
symlinks from these names to the unit filename. Note that not
all unit types support such alias names, and this setting is
not supported for them. Specifically, mount, slice, swap, and
automount units do not support aliasing.
WantedBy=, RequiredBy=
This option may be used more than once, or a space-separated
list of unit names may be given. A symbolic link is created
in the .wants/ or .requires/ directory of each of the listed
units when this unit is installed by systemctl enable. This
has the effect that a dependency of type Wants= or Requires=
is added from the listed unit to the current unit. The
primary result is that the current unit will be started when
the listed unit is started. See the description of Wants= and
Requires= in the [Unit] section for details.
WantedBy=foo.service in a service bar.service is mostly
equivalent to Alias=foo.service.wants/bar.service in the same
file. In case of template units, systemctl enable must be
called with an instance name, and this instance will be added
to the .wants/ or .requires/ list of the listed unit. E.g.
WantedBy=getty.target in a service getty@.service will result
in systemctl enable getty@tty2.service creating a
getty.target.wants/getty@tty2.service link to getty@.service.
Also=
Additional units to install/deinstall when this unit is
installed/deinstalled. If the user requests
installation/deinstallation of a unit with this option
configured, systemctl enable and systemctl disable will
automatically install/uninstall units listed in this option
as well.
This option may be used more than once, or a space-separated
list of unit names may be given.
DefaultInstance=
In template unit files, this specifies for which instance the
unit shall be enabled if the template is enabled without any
explicitly set instance. This option has no effect in
non-template unit files. The specified string must be usable
as instance identifier.
The following specifiers are interpreted in the Install section:
%a, %b, %B, %g, %G, %H, %i, %j, %l, %m, %n, %N, %o, %p, %u, %U,
%v, %w, %W, %%. For their meaning see the next section.
