[Techtalk] trying to find a question that _is_ "too dumb"

[perimorph]

Hi all..  After almost 5 years of using Linux exclusively, I _still_
can't figure this out!

What does the "s" in "sbin" stand for??

I know "bin" is for "binaries", but I just can't figure out what that
"s" is for!  Please fill me in..  It's like that feeling you get when
you just _know_ your two best friends are telling each other in-jokes,
and you don't have a clue what's going on.
