If I understand http://www.debian.org/releases/stable/i386/apcs04.html.en correctly, then yes. I can guarantee, as long as you don't have udev rules, or other deliberate commands for renaming, including, perhaps by initrd, that no other Linux user will have a disk renamed. Hotplug devices might differ. I am not sure if hotplug devices actually require such rules to guarantee stable names. -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe". Trouble?
