That's a bad idea. Changing systemwide hostname resolution for a unit test has huge side effects for a disposable use case. Please don't do this.

It would be better to do something like mock gethostbyname() in a unit test mock resolver .so and use runtime linker hints like LD_PRELOAD to make sure the unit test binary links to the mock instead of the system resolver.

Is there a way to set a /etc/hosts setting below or an equivalent one
in a RPM spec file? The rubygem-mysq2 RPM package's unit test needs
the setting to run SSL tests in the %check process of the
rubygem-mysql2.spec file.

```
$ cat /etc/hosts
...
127.0.0.1 mysql2gem.example.com
```

As a reference, here are the upstream mysql2 project's settings.
