I use FC6 and also Dapper Drake and Feisty Fawn as well as Debian Etch and CentOS for server applications. And about ubuntu sudo you are right only the first user can do it, unless later on you configure another one in the sodoers table, but as default only the first user. Withouth wanting to start a fight, I may think this distro is even more secure for not having root user, (actually it has, but has no password so you can not use it, unless you run sudo passwd root and put a password) because the hacker need to guess your username and your password to gain access to the server, not only the password. regards, -- Guillermo Garron "Linux IS user friendly...
