Um, I build xfstests on Debian Stable; other people build xfstests on enterprise Linux distributions (e.g., RHEL). I'd be really nice if we don't add a rust dependency on xfstests anytime soon. Or at least, have a way of skipping tests that have a rust dependency if xfstesets is built on a system that doesn't have Rust, and to not add Rust dependency on existing tests, so that we don't suddenly lose a lot of test coverage all in the name of adding Rust.... - Ted
