@gogol: You are 100% correct. I only use ext2. and ext3 and above will have to be customized manually as you have done. Thanks.

@shin: In your situation, you only interest in copy between mmc1 and mmc2, I would recommend cpxxwf.txt from thread #6. Once you get it working, I would make a button using personal menu,
(you already did, change cpxxwf.txt to cpxxwf.sh and chmod +x etc)

command to execute: ./cpxxwf.sh
and check run in terminal and run as root, and pick a symbol.

This script requires ext2 partition already available and will clone between mmc1 and mmc2 at will. As implied, this clones only the OS, will leave the data part, FAT16, intact.
From now on, you just have to the button, you get a fresh copy! I have used it more than 60 times in the last 2 weeks when I am testing progs. It works just like the restore program in MSwindow$.

Regarding the size of the partition, mmc1 and mmc2 does NOT have to be exact, and source smaller than target is also NOT necessary. I have successfully clones between 520 MB and 800 MB with very little programs. Just my guess, as long as the data is under 500 MB, even if you copy the 500 MB to the 800 MB partition initially, when later copy the 800MB OS back to 520 MB with no difficulty. Play with it and see what you think.

**** Be careful with mmc1 and mmc2. There is a bug in N810 to switch mmc1 vs mmc2. The patch to correct the bug is a little over my head. Good luck,
