The sudoers file has LOTS of settings. Some fun ones are to make it
insult you every time you type the wrong password. :-) (It says thing
like, is that you Dave?) But the reason I wrote this is because once
you sudo and type your password, the second time it does not ask for
the pw. This times out in something like 5 minutes. If you plan on
living in Sudo land you can change this to something like 60 minutes.
I personally almost never use sudo for more than 2 commands in a row
so a few minutes is fine for me.
