[Instructions how to become root]

Thank you for your effort to explain how to become root. But, sorry, it 
seems we were'nt talking the same language. I do know how to become root 
and how the prompt might look like. I just don't think it is obvious that 
a command should be used with sudo, if there is only a '#' as an 
indication. Probably I should have written it more precisely.

OK, that looks nice, but is it really that way with Ubuntu? I didn't know 
because I usually change the prompt according to my preference (e.g. red 
background for root). Therefore I started Kubuntu 7.10 Live CD. The 
prompt is "ubuntu at ubuntu:~$" for the normal user 
or "root at ubuntu:/home/ubuntu#" for root. I think it looks the same after 
a normal installation. So, the '#' or '$' seems to be only the last 
character of the prompt.

And that's what I think isn't useful. If somebody asks for a command on 
the list, it should not be expected that he sees or even knows the little 
difference between a '#' and a '$' in front of the real command. If I 
tell someone a command which should be run as root, I would either 
write "sudo some command" or I would mention that it should be run in a 
root shell.
