See tianon/gosu@fd60171 and tianon/gosu@f87df69.
The basic problem is that an invalid name like
bogus
will quietly run asroot
instead of being denied entirely (which those test updates look for and this change is verified to fix).I've run this updated implementation successfully against all of the test cases in https://github.com/tianon/gosu/blob/f87df69c868e19f7258b4facb7c2472d76d98dda/Dockerfile.test.
