I would suggest to add a note in the end of chapter n
I would suggest to add a note in the end of chapter nĀ°2, regarding the chance to pass the "mem=XXXMB" (e.g. mem=128MB) parameter to UML kernel. Doing this, i fix the "no space left to make device nodes" error in UML booting process, like reported (for example) in this forum topic: http://forums.gentoo.org/viewtopic-t-362567-start-0-postdays-0-postorder-asc-highlight-uml+space.html
Thanks for reporting; I added your suggestion. Fixed in CVS.
