That is not there. > Ideally, we should not be identifying data by the device that stores it. It's better than the standard *NIX way (topology), but it still isn't safe because of removable storage. Consider a system with multiple removable ATA HDDs. If the bays connect to the host system via USB<->ATA bridges, the serial number that the host sees will be that of the bay, not the HDD itself.
Using volume labels or UUIDs in /etc/fstab is much safer. It works with everything except the root fs (could be fixed in 2.5, I suppose) and swap devices (impossible w/o changing the format). Device names must still be stable enough to allow for fdisk/format without any surprises, though. -- Mark McClelland [EMAIL PROTECTED] PGP public key fingerprint: 317C 58AC 1B39 2AB0 AB96 EB38 0B6F 731F 3573 75CC _______________________________________________ [EMAIL PROTECTED] To unsubscribe, use the last form field at: https://lists.sourceforge.net/lists/listinfo/linux-usb-devel
