Dear Colleagues,

Have you ever tried to boot FreeBSD from a GPT partition with grub2 (no UEFI)?

In my test layout, /dev/ada0p1 is the freebsd-boot partition and
/dev/ada0p2 is the freebsd-ufs partition. However grub2 says "invalid
signature" about both of them:

 grub> set root=(hd0,gpt1)
 grub> chainloader +1
 error: invalid signature
 grub> set root=(hd0,gpt2)
 grub> chainloader +1
 error: invalid signature
 grub>
