I helped write the suspend code in Jobset so feel free to tag if you find issues.

For initially unsuspend, setting NodeAffinity foreach ReplicatedJob Template should be enough.
But if the jobs are already created the node selectors should be updated on each of them.
I propose to do that in jobset_contolled in resumeJobSetIfNecessary function on Jobset Operator.

Any progress on this?

@mcariatm is working on this at the jobset side.

kubernetes-sigs/jobset#134

So it will take a bit of time.

Yes, I'm still working on it. On both sides kueue and jobset. I think tomorrow I will put all changes for kueue. Working on tests now.
