merge commits are disabled for all oVirt projects as per https://www.ovirt.org/develop/developer-guide/migrating_to_github.html

we can really just create a trivial wrapper and replace globally with e.g.
- uses: ovirt/checkout

+1

As this needs to be included in each project separately, then I'd say let's minimize available options to ensure maximum consistency across all oVirt projects

1. I don't know how, and would have to learn quite a bit of github, to do this. That's the main reason I neglected this in my TODO folder and didn't reply yet. Perhaps someone already did something similar and would like to take over?

Take a look at https://github.com/oVirt/upload-rpms-action
minus tests (I hope Janos is not looking)...that makes it a new repo, and license, readme, and yaml file with that snippet. that's it.


2. I already pushed (2 weeks ago) and merged (yesterday) to otopi, [1], which simply does the above.

3. Scott now pushed [2], to the engine, doing the same, and I agree with him. So am going to merge it soon, unless there are objections. If eventually someone creates an oVirt action for this, we can always update to use it.

Best regards,
