yggdrasil 0.2 used gRPC where 0.4 uses D-Bus. foreman_ygg_worker is only compatible with yggdrasil over grpc and this narrows the requirement. This is important because yggdrasil 0.3 is in EPEL 8 & 9 and yggdrasil 0.4 is in CentOS Stream 9.

theforeman/foreman_ygg_worker#21 is adding D-Bus support.

I think we could avoid the if-else and just lock it down? Since there is an inherent technology difference between the versions.

On EL7 rpm doesn't support rich dependencies and I don't think you can properly narrow it. The best you can do is add 2 Requires statements which rpm will evaluate separately.

@evgeni any thoughts?

Yeah, this. Or:

Requires: yggdrasil >= 0.2
Conflicts: yggdrasil >= 0.3

Which is technically more correct.

But I am fine with using rich deps and ignoring EL7 for those last breaths it still has (it won't get yggdrasil 0.3+ anyway, RIGHT?!).

I now added that in the else branch. I still think the rich dependency helps rpm, but that's also just speculation from my side.

Or rather, not sure I want changes, as it makes explicit that things won't work… but it blocks upgrades unless users pass --nobest

I like being explicit in that it's broken. Otherwise it just silently breaks.
