Hello,
A while back, I tried installing GRUB on a FreeBSD GPT system. GRUB
only installs to bios-boot partitions and while I could have changed the
freebsd-boot partition type on my system, I wanted GRUB to recognize
freebsd-boot partition types instead. I made some simple patches to
allow GRUB to install to freebsd-boot and solaris-boot partition types.
I've attached the patches if somebody wants to merge them in (or tell me
why this is a bad idea) :)
