 I remain confused.   What test is that?   Or tests that would be used on
 linux?
 
 If this is about some ATF test (the PR doesn't even suggest that though)
 then it would depend upon the test, some of them are explicitly testing
 NetBSD behaviour, to ensure it isn't accidentally altered (breaking backwards
 compat) and others test required behaviour, to make sure our implementation
 doesn't have design/impl bugs.
 
 Ideally the former kind would skip if the test isn't being run on NetBSD,
 but I doubt that many of them do.
