To run just the non-dangerous tests, you could do -g selftests/selftests -x selftests/dangerous_selftests. You can't simply use -g selftests -x selftests_dangerous as right now selftests is not being added to SRC_GROUPS. It would be nice to make it behave more like a normal group though... If it doesn't matter that these would run with -g all, I could just add it to SRC_GROUPS. If it'd be best to skip these during running -g all, I could also update get_all_tests to skip over the selftests folder. Do you think these should run with -g all? > > Or <cough> fsteststests.

What exactly do you mean?
