Thanks this is interesting!
I only got cc'ed on the cover letter and I'll slowly have a look on
the rest. A naive question -- I saw you did integrate this on gitlab
with your internal lab. How secure is this? Could we schedule weekly
builds that run on various remote labs and get results on actual
hardware? Or do we have to rely on users for that ?
Thanks
