Yes. Besides, it's only an integer, which isn't able to reliably identify a device. That's why I don't think this feature should be used. > > Which parameters do you have in mind? > > > I thought of it more like about instruction like: boot from strange > place or enter debug mode in early stage. You don't need additional parameters for that. Since both loader and loadee can take user input, user can tell the loadee to enter debug mode instead of the loader (press 'c', then set debug=something, etc). > > Doesn't PXE already handle this? > > > I'm not really familiar with it. Does it support multiple servers. Neither am I. I think we should have a clear idea on what our requirements for PXE are before discussing if we need to use boot parameters for it. > But still for me this feature is just an idea. I'm still not > persuaded myself whether it's needed. Maybe it's a good idea, or maybe it's not useful for anything. I think first of all we should exactly know what it is needed for. IMHO, we should be careful about adding interfaces just for the sake of having them. -- Robert Millan The DRM opt-in fallacy: "Your data belongs to us.
