If the branch is already in a broken state, please refrain from adding

extra new breakages. Stabilize it for a few days, merge into master,

then resume development on staging.

<para>

If you're cherry-picking a commit to a stable release branch, always use
|
|
<command>git cherry-pick -xe</command> and ensure the message contains a
|
|
clear description about why this needs to be included in the stable
|
|
branch.
|
|
</para>
|
|
<para>An example of a cherry-picked commit would look like this:</para>
|
|
<screen>
|
|
nixos: Refactor the world.
|
|
|
|
The original commit message describing the reason why the world was torn apart.
|
|
|
|
(cherry picked from commit abcdef)
|
|
Reason: I just had a gut feeling that this would also be wanted by people from
|
|
the stone age.
