Interesting things I learned about Linux 8.04
The FIRST user (set up at install time) is the only one who can use the
sudo command, unless that first user sets the other(s) up as administrator.
The sudo command is in preference to establishing a 'root' user. You can
become 'root' temporarily by entering *sudo -i* on the command line
(followed by your password). This gives you the *#* root prompt. To
leave this temporary account, type *exit* and press enter.
You can also create a 'root' account if you want. I didn't want, so
didn't bother to find out how. *sudo -i* is plenty for me! ;-)
