I submitted a version of the Linux i2c-tools (https://snapcraft.io/i2ctools) and it was flagged for manual review. This was built by snapcraft’s servers for 5 architectures automatically (amd64, arm64, armhf, ppc64el, and s390x), using the code from the kernel.org git repository. (My github project only contains a snapcraft.yaml to use the Makefile plugin and specify the upstream repo.)
The part I found weird was that only the build for s390x passed manual review. The other builds submitted at the same time oddly enough are still stuck in pending manual review. I’d have thought they would have been sequentially submitted and reviewed shortly one after the other to avoid a lot of work on the reviewer’s part.
Anyway, just a comment.
