Yes, I know.
But if the installer has setup (by its own) as default method for naming
devices the old one and I am not experiencing any problem with that, for
sure I won't change that. If it ain't broke, don't fix it.

I know, I know... but Lenny developers decided to go this way for any
reason and I will respect that. I'm aware that nowadays any modern
distribution is using "uuid" or "id" at least in "/etc/fstab" but as I
said, I still have not seen any good reason to change it.
