matthewcroughan: i have copied the nixosTests.login and added security.enableWrappers = false + pwaccess stuff, and the test is succeeding. Its screaming at me and i am definitely doing things wrong, but this might be progress?

Bad news is, pwaccess uses fgetspent_r / ~~fgetspent_r~~ fgetpwent_r which are unavailable on musl. Not sure yet how i'll fix that pain
