Testing ignition-dracut changes locally in Fedora CoreOS

1. Download the Ignition RPM source by cloning the following repository: https://src.fedoraproject.org/rpms/ignition

   git clone https://src.fedoraproject.org/rpms/ignition.git
   cd ignition
   

2. From the ignition-dracut repository you made commits in, push your ignition-dracut changes to your fork of the ignition-dracut repository (any branch is fine).

   cd ignition-dracut
   git push --set-upstream my-remote my-feature-branch
   

3. Find the commit hash of your last commit by doing git log. Copy this hash.

4. In the ignition repo from step 1, paste the hash in the dracutcommit macro, on this line https://src.fedoraproject.org/rpms/ignition/blob/a614d3e5a05cbc2788b0cba592a5ee96c9f4cd0a/f/ignition.spec#_70.

5. Change the dracutproject macro to your GitHub username where you forked the repo, so the specfile points to your fork, on this line: https://src.fedoraproject.org/rpms/ignition/blob/a614d3e5a05cbc2788b0cba592a5ee96c9f4cd0a/f/ignition.spec#_65.

6. Change the Ignition version to a high number, e.g. 99.0.0 on this line https://src.fedoraproject.org/rpms/ignition/blob/a614d3e5a05cbc2788b0cba592a5ee96c9f4cd0a/f/ignition.spec#_75. This is so COSA picks up your built version, as it will pick up the latest version when overriding.

7. Build the RPM by doing the following (this may require dnf install -y rpmdevtools fedpkg dnf-plugins-core first):

   cd ignition
   spectool -g ignition.spec
   dnf -y builddep ignition.spec
   fedpkg local
   

8. The built RPMs should be in a directory x86_64. Copy all of the RPM files from there, into the overrides/rpm directory in your COSA working directory.

9. From the COSA working directory, execute cosa build --force-nocache. You should see your custom 99.0.0 ignition and ignition-dracut versions included.

Minor: dnf-plugins-core

@zonggen Thanks, fixed!
