Hi all,
I've attached a patch to grub-install which adds an extra option for
specifying a memdisk to install and an option to specify an embedded
config which will be appended to the already generated embedded config
(written to $prefix as load.cfg). I don't really need the options to
be user visible, if that lowers the chance of the patch being
included. But its nice to have these options when you want it.
