I have an install on say sda6. I would like to 'copy" this to say sda8.
The reason, is to have a working backup of the partition, so if I do an upgrade or install new app, and it fails, I could always boot to working copy (ala time machine almost) But I believe since their are uids used in many places, not too mention boot loader, this is not possible?
swap is on its own partition.
