Actually, I believe it should be a global decision of the project
leadership. But I believe the word global to be important here. We
should decide together and then a common version to platform map
should be prepared by the integration team.

Single projects could still add additional overrides if needed though.

This actually means we get surprised and confused indeed. Please note
that nobody really told us that Fedora bits are not going to be
released anymore (see 4.2 release notes [1]) and whether we should
update the job specifications or not.

Integration team reported to the developers community that Fedora support was broken starting with Fedora 26 back on August 2017[1].

We also reported during the beta process that oVirt 4.2 would have not supported Fedora to user list  in November 2017 [2] since nobody fixed Fedora support in the meanwhile.

No request or direction about what to do with Jenkins fedora jobs has been issued since we (integration team at least) want Fedora support back in 4.3 but since we don't have yet a schedule for 4.3 we don't know yet which fedora version we'll target. In integration team we are now slowly enabling jobs on master for fc27 and fcraw (rawhide).

I'd like to clarify my own understanding re what should be done with jenkins jobs.

1. You can still, and are very welcome to, have and maintain fedora

builds/jobs for your projects.

2. Not officially publishing builds does not mean you can't build them, and

if you do, they are still published in the -snapshot repos, so users that do

want them, can have them.

3. If building for fedora will make the job(s) for your projects fail constantly,

either because you have bugs there, or because you rely on some infrastructure

packages (otopi, ovirt-setup-lib, etc) to work on fedora (and with python3),

then it probably does not make sense to build yet for fedora - this will simply

add noise.

4. If OTOH your project is independent, and works just fine on fedora, you are

more than welcome to build (and then publish in -snapshot). Doing this will

very likely make the eventual transition to "fedora is supported" much smoother.

5. This is really a per-project decision, so unless we start having cross-project

discussions about this, you should decide for yourself. Just keep in mind that

eventually we'll have EL8, which is very likely to be more similar to current

fedora than to current EL7, so better prepare... (saying this also mainly to

myself!).

Best regards,

Right. But we have something very similar now: spreadsheets with lists
of packages that are missing from a new version compose. I do not see
too much difference actually..

> Personally I prefer that decisions remain distributed

I agree with who decides things (all of us). But the decision needs to
be documented. Do we have any (easy to find) list of expected
platforms for given a release?

The decision then might be compiled into a file we could include and
stay current without manual edits.
