I spend a bit more time bisecting the various core18 snaps to see at
what revision the failure started to become reproducible. Interestingly
I found that it started with r2208 AFAICT. It's all a bit annoying
because it's a race so I don't trust it 100% but the previous r2206 got
2 good runs in a row but the r2208 failed also two times in a row. The
only change there is cloud-init
https://people.canonical.com/~mvo/core18-changes/html/edge/'20210928'r2206_'20210930'r2208.html
which might explain why we see the failure in our integration tests in
GCE but not inside QEMU. Unfortuantely the cloud-init diff is pretty
big.
For reference, here is what I ran:
