[PATCH] --config-file support to grub-install

[Felipe W Damasio]

        Hi GRUB hackers,

	Though the grub-install shell script is very nice letting the user 
specify things the location of the grub shell, it doesn't let the user 
override the location of the configuration file..which is kind of 
painful for users (or newbie admins) who don't know their way around 
the grub shell and want to do this.

        This patch add this option.

	I know that at least one distribution (GoboLinux) would like this 
option on grub-install.

        Please consider applying.

        Cheers,

Felipe
