Ok, here is a question. I am using encrypted swap, with a script that creates a loopback off of my swap partition on each boot. The problem is that if a drive fails and I reboot, the device name for the drives will change. My mkswap could potentially wipe out the wrong partition in that case. Now, I know that won't happen currently because my swap partitions have higher partition numbers than any of my data partitions. However, I'd prefer to test for this possible condition. Is there any way to get a unique identifier for a drive - such as a UUID? I see hdparm -i returns a serial number (which I'd need to parse out), but it doesn't work for SATA drives. Any ideas? Then I could test the drive's unique ID before I start wiping out partitions... -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.7 (GNU/Linux) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iD8DBQFGoPOrG4/rWKZmVWkRAuraAJ4ulJpnWFYjW/0ISPXZGk4tKGAbpQCfbVUf mFNEmoEx/KItJYnJzjXQs4Y= =xv13 -----END PGP SIGNATURE-----
