Understand it before acting on it, and take salt with item 4. If you 
don't know what you're doing you will stuff things up. I went to a LUG 
meeting once where one of the Gods of iiNet was to speak on Linux 
security. He was a little hoarse so someone else stepped in. Between 
them they enumerated lots of binaries that "don't need to be setuid root."

I took the advice and borked several things including my ability to print.
