Hmm, I wonder what happened here. We've been very careful to keep grub and grub-efi separate. The entire directory lib/grub/x86_64-efi shouldn't be available in the "grub" package output - and I checked on master, it isn't. Good. So that leaves automatic target selection as the culprit. And indeed, there's a call to grub_install_get_default_x86_platform in util/grub-install.c . And that checks for availability of /sys/firmware/efi and if it exists, defaults to EFI. I think it's a bug in grub to do that for a grub which doesn't have EFI platform support. :P We could just always pass i386-pc in install-grub for i386, but then we lose i386-ieee1275 (which I have never heard anyone using so maybe not so bad). Please report a bug with grub...
