I did it this exact way when I bought a new HDD for my laptop last Christmas, because then I could still use my normal system instead of booting a LiveCD and waiting for the sync to finish (which could take half an hour). Copying 16GB from a laptop HDD to another one via USB is not that fast. Only before everything was done and I was ready to boot with the new HDD, I did another rsync with logged-out users on TTY1, which takes but a minute. IIRC I didn’t even boot a live CD. And even IF there were some flaws in the mirrored system, there’d be no harm done as I have the original still around to amend them. -- Gruß | Greetings | Qapla' Crayons can take you more places than starships.
