In order to get Mini-OS master branch tested by OSStest, use it for
xen-unstable.

There are some Mini-OS patches pending, of which at least the Mini-OS
netfront fix should be committed as it will be required for qemu-stubdom
to work.

I'm afraid this, effectively reverting 82c3d15c903a ("minios: Revert recent
change and revert to working minios"), would set us up for the same problem
again that was dealt with there. IOW you're re-proposing a change of yours
(e013e8514389 ["config: use mini-os master for unstable"]) which was
subsequently reverted, without spelling out what has since changed.

How do you suggest to proceed then?

Will every Mini-OS commit require to be followed by a Xen commit then,
which will either result in a test success, or in a revert of that Xen
commit?

It should be noted that the presumed interface change in Mini-OS causing
the failure in OSStest last year has been reverted by me.

Once the two trees are assumed to be fully decoupled, and once a push
gate has been put in place for mini-os.git, we can do what you suggest.

That is how the current arrangement works.  That's strict coupling.

If you want to decouple it, that's possible.  Ie, run a separate
osstest "branch" (ie, series of flights) for mini-os; have a separate
osstest-tested mini-os output branch, etc.

Wei, if we were to do that, should we have a "staging" and "main" for
mini-os in the main mini-os tree, or what ?
