I created an account just for this tutorial.
I tried your method of remastering as I like the way it works.
But did however made the mistake of trying to do the source/master directory on a ntfs filesystem. this caused all persmissions to be lost while copying and after the remaster nearly everything was broken.
Of course I was going to rage on this tutorial when I realized it maybe couldve been because it was ntfs and took another memorystick and formatted it to an ext2 filesystem. this did the job

is there a way to not break anything while still copying to a ntfs filesystem?
