The 'D' is now capital to clarify pronunciation. DBus service name is kept as '/Tuned' not to break backward compatibility. This will also need update of downstream tests which rely on the specific output strings containing the name. Signed-off-by: Jaroslav Škarvada <jskarvad@redhat.com>

= Inheritance between TuneD profiles
|
|
|
|
*TuneD* profiles can be based on other profiles and modify only certain aspects of their parent profile.
|
|
|
|
The `[main]` section of *TuneD* profiles recognizes the [option]`include` option:
|
|
|
|
[subs=+quotes]
|
|
----
|
|
[main]
|
|
include=[replaceable]_parent_
|
|
----
|
|
|
|
All settings from the [replaceable]_parent_ profile are loaded in this _child_ profile. In the following sections, the _child_ profile can override certain settings inherited from the [replaceable]_parent_ profile or add new settings not present in the [replaceable]_parent_ profile.
|
|
|
|
You can create your own _child_ profile in the [filename]`/etc/tuned/` directory based on a pre-installed profile in [filename]`/usr/lib/tuned/` with only some parameters adjusted.
|
|
|
|
If the [replaceable]_parent_ profile is updated, such as after a *TuneD* upgrade, the changes are reflected in the _child_ profile.
