The article mentions having each partition with a different encryption key. Andrei thought I would have different passwords on each. The idea of doing that never occurred to me. Something must be eluding me: why having different password or keys for partitions in the same disk?
For the same reason you should have a different password for each resource on the same Internet. Because compromise of the password for one partition does not automatically allow access to other partitions.
To me the resource is the computer. It is the same as the car that has three doors and an ignition, all using the same key. It is not more vulnerable. Anyway, the main partition holds a key that opens the other partitions. -- Cheers / Saludos, Carlos E. R. (from 15.4 x86_64 at Telcontar)
