Moinak, thanks for the link. But then, you miss the point. Yes, rsync would surely work as long as the full tree is available on the server to synchronise with the local box. Rsync is not geared at peeking into individual isos and working out diffs, to do local jiggery puggery. My suggestion was, since most people download isos with every release, it may be a matter of just popping your old CD into the cdrom drive, and downloading the diffs which assemble into isos locally. (Though I am not sure, with the amount of "packing"/ cramfs stuff in each Belenix CD can be successfully exploded). The amount of stuff packed into each Belenix CD is unbelieveable ! I did an online upgrade from 2008.5 to 2008.11 on Sat night. I had to d/l almost 1.2 GB of stuff, which ran throughout the night and into the morning ... Bish
