What I'm asking for here is: from within a Debiannish linux, a tool (ideally graphical, but w/e) that you point at a hard drive, that:
- Formats this new hard drive appropriately, making it bootable and doing grub-whatever
- Installs the same packages onto that device as are on the host system, and
- Optionally copies over user account information (/home/*, passwords, etc
- Optionally copies over whatever's in /etc or /opt
...and ends with a hard drive I can plug into another system and boot.
That's the last solution I'd think of for that particular problem. And essentially, most Linux users would script something up. How often do you want to do this? What about a PXE Server and preseed file? Turn the new machine on, network boot it, make a cup of tea, log in. That's how I'd solve it anyway.
