Is this something more than the signed repos PR?

Look at the work outlined in the link above. I think Dennis Gilmore wanted to discuss the proposed design but there is more work than just signed repos.

This will need signed repos to be in

@mikem This is moving the making of the dvd iso and the install trees into koji as koji tasks

@ausil Is this still valid? If yes, are there any clear requirements?

@jgreguske was the one that laid out the design, I just filed the ticket here, Jay would need to weigh in on if it is still desirable

It is still desirable to have Koji build installation media, but it is definitely not in my Q2 priorities (speaking internally about RH there). I've never understood the current model where only Pungi can build it. Koji is a much better place.

The implications of enabling Devs to build their own installation media is compelling to me. In the distant future we could do away with milestone composes, just take the latest that passed and ship that. Devs could be responsible for discovering dependencies are missing.

This issue has been migrated to Fedora Forge:

Please continue any further discussion there.
