I didn't know you had 1 in mind. Yes, I think it's better to restrict us to 2 for now. I don't really see a big benefit in 2 vs just using "grub-mkimage -m", but I suppose if it's not too intrusive it doesn't harm. > > Also, I can only think of very specific situations in which this interface > > would be useful (that is, when firmware has only a linux loader).

I'm not very familiar with multiboot, but it supports modules (an arbitrary number of them, I think). Then again, we still need a use case before adding a feature. The obvious use case for having lnxboot is booting from firmware that only supports booting Linux, but for other stuff I still don't see it. I mean, the initial purpose of memdisk was that you could _embed_ data in core.img itself. Using it as a loader feature sounds a bit contradictory to me... perhaps if you explain what situations do you have in mind where this would be helpful, I'd understand your point better. -- Robert Millan <GPLv2> I know my rights; I want my phone call! <DRM> What use is a phone call… if you are unable to speak?
