unsure if these are applicable to Debian, but creating this bug to track here. my original comment:

I'm imagining something like installing and running a list of software packages, or maybe even a language runtime, and just checking certain simple interactions between the software and Debian itself (syscalls, etc). Maybe these are more integration tests of the underlying software and not Debian.

just sparking a little discussion on whether we think these apply to Debian at all. can close if we decide they're not going to happen.
