Done. I did a deeper dive in how the testing is done for functions that require super user and saw some tests following this path: 
```
if (LIBC_NAMESPACE::getuid() == 0)
    do_something();
```
I was not sure it would be a good idea to have it like in the test for CI, so I wrote it a little bit differently.
