Hello all. Based on the information from http://mjg59.dreamwidth.org/7468.html I intend to add support for such install. It requires a small HFS+ volume mounted at /boot/mactel. I also simplify handling of EFI directories by adding explicit option to specify it and removing some "compatibility" kludges (they don't make anything compatible with anything since "old behaviour" was mostly not to install at all) which made the code in question difficult to maintain.
Matthew will perhaps give a more thorough response, but I would like to add a few quick comments.
Matthew also created http://www.codon.org.uk/~mjg59/mactel-boot/ , so there seems to be some duplicate work there.
His approach is discussed further on https://bugzilla.redhat.com/show_bug.cgi?id=755093 .
A quick summary is that it (in my opinion) is a bit unclear what Macs _really_ needs. There are several ways grub can be used to boot Macs, and it is not completely clear whether HFS blessing or HFS is necessary at all. The Mac boot loader detects FAT partitions and will by default also boot from /EFI/BOOT - also on the system partition. The OS/X "Startup Drive" configuration is a bit more sensitive, but it seems like what it writes to PRAM/VRAM is more important than the HFS blessing.
