Thanks Marty, your rsync switch is the most comprehensive one I've seen.
Just FYI, when cloning the root partition, there are directories that
don't need to copy over, like /tmp, /proc. So you may want to add
--exclude switches to your script next time.
Further, with modern Linux that uses udev, like what you are using, the
/dev and /sys don't need to be copied either. You can --exclude them as
Moreover, you may want to reconsider whether you want to clone
/var/cache/apt/archives next time.
The point is that I don't want to clone more than necessary.
Does anyone know if there will be any side effects if I don't clone the
