Hi Helen,

Thanks for working on this

4.5 :)

One thing I'm wondering here is how we're going to cope with the
different requirements each user / framework has.

Like, Linus probably want to have a different set of CI before merging a
PR than (say) linux-next does, or stable, or before doing an actual
release.

Similarly, DRM probably has a different set of requirements than
drm-misc, drm-amd or nouveau.

I don't see how the current architecture could accomodate for that. I
know that Gitlab allows to store issues template in a separate repo,
maybe we could ask them to provide a feature where the actions would be
separate from the main repo? That way, any gitlab project could provide
its own set of tests, without conflicting with each others (and we could
still share them if we wanted to)

I know some of use had good relationship with Gitlab, so maybe it would
be worth asking?
