Merge lp:~vorlon/britney/turn-on-arm64-slowly into lp:~ubuntu-release/britney/britney1-ubuntu

[Steve Langasek]

We don't have arm64 autopkgtest capacity to handle running the autopkgtests consistently for devel, but we have worked through setting a baseline for the stable releases (xenial and forward) and our single test runner might be able to keep up with the autopkgtest demand just from SRUs. Turn this on initially for xenial only in order to see.

Hmm, seeing you write this makes me think that you're not aware that
bos02 is up and running. I suppose I forgot to communicate this widely
enough - I thought you were aware because I've been watching the queues
for the other releases fill up in sequence as the previous one finishes.

I think we *do* have capacity to turn on proposed-migration for arm64
for every release if we want to. Currently we have 40 workers handling
arm64 and s390x.

Go for it. I thought you were establishing a baseline by doing an
initial run. If you are doing this, please feel free to turn on releases
once the baseline run is finished. If you don't think that is important,
please also feel free to turn on all releases right away if you think
that's best - with no baseline run it shouldn't be much of a burden for
bionic even.

Cheers,

Right, I was unaware arm64 in bos02 was live. Given that this is the case, I'm abandoning this merge in favor of enabling arm64 for all series as soon as the current baseline run finishes.

Rolling enablement of autopkgtests for arm64 in britney: turn it on first only for xenial and see how it goes with the SRUs
