I actually forgot to mention a very interesting case that Athos and I faced while working on the sbcl bootstrap. The dep8 test for the osicat package was initially failing on amd64 and blocking sbcl from migrating, so we started checking what could be happening. Strangely, the failing test had to do with a check for a non-existent username in the system; this check (performed using the '(user-info)' call) was returning a valid user instead of nil. Neither Athos nor I were able to reproduce this problem locally, even after trying several incantations when invoking autopkgtest. I also tried checking if the problem would manifest on canonistack, to no avail. An autopkgtest run against a PPA build also succeeded. We were really puzzled by this. All in all, we spent several hours building and testing the package, and every time it succeeded. I performed a no-change upload in the hopes that rebuilding the package would have an effect on the test result, but it didn't. I was running out of ideas (and energy) when, by Monday night, I started suspecting that the root cause could be the fact that the trigger list for the failing tests had only sbcl in it. I decided to retrigger the test passing sbcl *and* osicat in the trigger list, and it finally succeeded. I have absolutely no idea what happened, and I don't have access to autopkgtest's infrastructure in order to debug the problem. But I thought I'd mention this very strange case here just in case someone faces a similar scenario.
