Hi there...without getting into some debate about freedom which I am not interested in doing, you are free to mess up your system any way you like. I am not preventing anything. I was/am trying to make the experience smooth for people who might not be as comfortable with Debian vs other environments.
when you are "sudo"ing something, you are doing it with root privs... Want to launch the file manager as root? open a terminal and sudo "command" and you can delete, mess up whatever you like.
If you want a root account, follow the steps below to enable.
first - enable shadow passwords (reference my alert in the forum about hardening password security anyway).
In a terminal
'sudo pwconv'
then
'sudo passwd root'
enter your sudo password (your current user password)
then enter what you want as a root password twice. (follow the prompts)
then you have a root account and you can 'su' , logout and login as root (of course everything will look much different). etc.
enjoy
