Hi all,
As discussed in #grub irc, I think going the --boot-directory way as
phcoder suggested will lead to unnecessary complexity. I would prefer
directly mentioning the path to grub_prefix dir, as in case of uefi installs
the prefix dir could be anything (/efi/grub, /efi/grub2, /efi/grub_custom,
/efi/redhat, /efi/ubuntu etc.). Using --boot-directory in such a case also
requires --bootloader-id etc. to be provided.
Proper GRUB_PREFIX is required for video.lst and locale_dir setting
in grub.cfg. The patch with --prefix option is at
http://pastie.org/2763921. Please give your views.
Regards.
