The systemd
class provides support for recipes
that install systemd unit files.
The functionality for this class is disabled unless you have "systemd"
in
DISTRO_FEATURES
.
Under this class, the recipe or Makefile (i.e. whatever the recipe is
calling during the
do_install
task) installs unit files into
${
D
}${systemd_unitdir}/system
.
If the unit files being installed go into packages other than the
main package, you need to set
SYSTEMD_PACKAGES
in your recipe to identify the packages in which the files will be
installed.
You should set
SYSTEMD_SERVICE
to the name of the service file.
You should also use a package name override to indicate the package
to which the value applies.
If the value applies to the recipe's main package, use
${
PN
}
.
Here is an example from the connman recipe:
SYSTEMD_SERVICE_${PN} = "connman.service"
Services are set up to start on boot automatically unless
you have set
SYSTEMD_AUTO_ENABLE
to "disable".
For more information on systemd
, see the
"Selecting an Initialization Manager"
section in the Yocto Project Development Tasks Manual.
