Why should this not work? The mirror repo is already cloned/fetched/checked out, right? It's here on purpose to ensure early return without overwriting all of /var/cfengine/masterfiles with the same revision.

The problem here I think is that we have copied HEAD into temp_stage so it is always the same.

As-is I never got updates. There may be another cause but if you check my notes in ENT-11970 you might see some details that shed some light on the situation.

I imagine it worked for you while testing so not sure what is going on. Maybe grab a nightly build and try it out there. That's what I was doing.

Unfortunately, I didn't test this very much. I was planning to test the whole set of changing how and where from masterfiles-stage.sh is run, but then I got busy with other things before finishing the set.

Oh, I see it now! But IMHO the error here is to compare with ${temp_stage}, we should compare with $MASTERDIR (or whatever it's called) and keep doing it here.

yup, looks like that's enough: #5579 (and https://github.com/cfengine/nova/pull/2284)

Might be nice to mention in a comment here that we are abusing the previous function setting a global variable so we know local_mirrored_repo
