"sudo su" and "su" have a fundamental difference, vital in corporate networks: The former uses the user's password for authentication and sudoers for authorization. The latter uses knowledge of the root password for authorization and authentication. See my other post in this thread. On the work servers I enforce "sudo su" OTOH, "sudo su" is indeed pretty pointless on a single-user machine. I never bother with sudo on this gentoo notebook for instance. -- alan dot mckinnon at gmail dot com
