-====== Mi configuración de SUDO favorita ======
-Desde que ubuntu usa sudo para ejecutar las acciones administrativas, este simpático programa de seguridad se ha puesto de moda. Y cómo no, yo también me he subido al carro. Tengo una configuración de sudo que no me pide contraseña, simplemente mi usuario está entre los que se les permite ejecutar todo como superusuario.
-Esta es mi configuración de sudo (ver abajo). Tampoco es //rocket science//: es la configuración por defecto de SuSE con unos retoques aquí y alli para que:
-  * permita ejecutar todo a ciertos usuarios sin preguntar contraseña excepto:
-  * passwd y visudo
-¿Porqué? pues para mantener algo limitada la posibilidad de "escalar permisos", aunque es cierto que con hacer "sudo su" ya está todo ganado, pero bueno...
