[oclug] Read Write Execute, what is S?

[Andrew Hutton]

setuid()

That means, when the program executes, it does so with the uid of the
owner.  In most cases this is root since you generally need to be root 
to make it work.

This can be dangerous since any setuid(0) application has full reign
of your system.  (Enter ACL's to deal with this, but ACL's are way outside
the scope of this commentary).
