GRUB Legacy did this also, so I'm unsure what you're arguing. On GPT, GRUB2 uses partitioned space (whether EFI or BIOS firmware is used). > (It isn't always 62 sectors, either.) As it turns out I don't consistently get a failure with a 1st partition starting at LBA 63. Usually the GRUB core.img is ~26K which will fit into that MBR gap. But sometimes it's bigger and I don't know why, and then it fails, and subsequently anaconda fails.
