Fanoush: You've provided us with lots of good information to think about, and act on as appropriate

1) "Is using 'on' OK in this context or is using 'in' or something else better?"

Thanks for the clarification here. Now that I understand it better, I believe that the issue does not concern whether "on", "or" or "in" would be better, but rather the use of the word "either." I assumed that you meant "or" because of the "either." Am I making myself sufficiently clear here?

2) "I haven't seen this issue on my device yet so I guess it is safe to clone the system anytime.... If the system boots OK from flash it should in theory boot also from mmc if the copy is exact (i.e. no mistake is made while cloning).... There may be differences due to two mmc slots...."

As you haven't had opportunity yet to pursue this issue of a large card and the N800's two slots, I will be experimenting with all this when I get my N800 and report back to you and the forum, and no doubt also seek further advice. From what I can make out from your README, I could possibly also have multi "distros" on just one card (if big enough) and boot to each of their separate ext2 partitions from your boot menu, and wouldn't even need to effect this with separate cards. Anyway, much to consider. Thanks again. Regards, Jim
