Hi Peter,

That's not a stupid question at all.  I don't know the answer, I've not
tried.  However it if works, I think it would be a good thing in some

On a related note, there is some fledgling code in bin/ to
support initramfs.  I'm not sure it that might be another option too.
Again I've not really played with this much.

Regards, Stuart
