Hmm. Do you have a few statically built binaries that could be tested
without installing a whole distribution? Something real and meaningful
enough that it actually exercised a few real system calls, but not
something that needs to bring in 50 different shared libraries?

Something in /sbin, perhaps, that is still runnable by a regular user
and doesn't require some distro-specific /etc layout etc, so that it
would work even if you don't run Debian at all? Maybe some shell
binary or something?
