[Bug 1302407] [NEW] Recent Grub2 grub-install has issues with my macboot efi dual-boot configuration

[Benjamin Geese]

Public bug reported:

I managed to install Ubuntu 14.04 on my MacBook exactly as i whish
thanks to improved EFI support and this guide:
http://glandium.org/blog/?p=2830.

This enables to boot Ubuntu without reFit or similar, but requires the grub-install to work on a hfs partition. In earlier versions of GRUB2, you simply could replace some lines in the grub install script, but that is now a binary, so that fix is no longer possible:
if test "x$efi_fs" = xfat; then :; else
    echo "${efidir} doesn't look like an EFI partition." 1>&2
    efidir=
fi

While a still am able to boot, this taints my dpkg-database as whenever
a package like the kernel is updated:
