The grub ebuild does mention the optional dependency on dev-libs/libisoburn for grub-mkrescue. But it does not mention sys-fs/mtools, which is equally required for it to work (at lest for EFI targets). Is there a particular reason there's no use flag to pull in those dependencies? I wondered why I had those installed and in my world file at least once so far.
