It's a bad test. Sure, it's not perfect, but it's better than not working at all. The heuristic seemed good enough at first glance, and autopkgtest-build-qemu seems to have dealt well with it over time, hence why I proposed simply carrying over the code. > There is also another option: convince Debian kernel maintainers to add > linux-image-virtual to their list of meta-packages and let it depend on the > right meta-package depending on the architecture.

I guess this could be raised with the Kernel Team, though I suspect it might take a bit of convincing. If an exact solution is the goal, one approach might be to rely on RELEASE and see if debootstrap's /usr/share/debootstrap/scripts can be used to map to Ubuntu. Best, Christian
