No i think there is no solution, maybe LUCK lol
the best thing is to do a live install multipartition and to assign one part(ext2) to changes
easy to do if you follow my tutor in my signature
i run actually a 160 Go western digital usb 2.5 hd
there's a boot part, a swap part, a changes part and a data part
really i never get pb with this method, but it consume more ressources than a real install.......
BT IS INTENDED TO BE LIVE, WHY DO YOU WANT IT REAL ??????
