Congratulations! One of the builds has completed. 🍾

You can install the built RPMs by following these steps:

• sudo yum install -y dnf-plugins-core on RHEL 8
• sudo dnf install -y dnf-plugins-core on Fedora
• dnf copr enable packit/sosreport-sos-3453
• And now you can install the packages.

Please note that the RPMs should be used only in a testing environment.

Looks good on its own (just the CodeQL note) - where do we anticipate this being used? Do we need to link up any existing policies to it now or is this prep work for something coming later?

[TurboTurtle]

To keep CodeQL happy, let's add a comment here explaining either how we got to this exception (header/foooter output?) or some similar note to future-us.
