The important tip that I didn't get for ages was using typing

1. '#' means 'you're logged in as a user'
2. '$' means 'you're logged in as root'
I think you've said that backwards ;]

Yup. Notice, though, that with the original Fedora Core 3 setup, the
prompt won't get changed correctly if you are using (t)csh. Fixed in one
of the updates, I think.
4. If you type
# su -
it will ask you for your root password and behave as if you'd loged in
as root. I don't understand why but it works better than
# su root
su - gets root's shell, su keeps the user's.
Which means, among other things, your environment variables are still
your own user's.
I'm sure some else can explain better, but basically su isn't really
'becoming' root.
