Shouldn't that "on" be "or"?
no, linux flasher runs on the PC and uses USB cable to communicate with the tablet. Second option is cal-tool which runs directly on the tablet. Is using 'on' OK in this context or is using 'in' or something else better?

In fact this sentence is not mine. This is Wiki, anyone can edit it including you. You can click 'Get Info' link on wiki page and then select versions and click 'Diff' to see who added what.

I haven't seen this issue on my device yet so I guess it is safe to clone the system anytime (and I do it like this). 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). This theory works for me on N770 both with IT2006 and also IT2007 (hacker edition) which is made from N800 firmware. I still don't have big card for my N800 so I'm not sure how cloned system works on real device. There may be differences due to two mmc slots (which is not same as N770 with IT2007).

I know some people reported this reboots after cloning but it can still be some mistake when doing it. Or it can be also some specific installed application which does this. I guess Canola does some funny things with the device but I never installed it so I don't know for sure. Maybe it is related to scanning mmc cards for media files after boot.
