If this hook is included with `dracut`, this check is likely unnecessary.
Albeit, we should use `usr/bin/dracut` instead?

But, this hook is depended on both `dracut` and an efi file provided by `gummiboot`.
I'm not sure if it's better to split it out and explicitly `depends` on `gummiboot`?

**I, myself,** don't care about the broken system _if their owners choose to break it_
