|I'm pretty sure you mean the set-uid bit, not the sticky bit.  The
|sticky bit causes an executable image file to remain in virtual memory
|even after it has finished executing, so that it does not have to be
|loaded when run again.  It is common to do this to executables that
|are used a LOT like ls and csh.  Clearly this is meaningless for a
|directory.  The setuid bit, which is what shows up as an `s' in an ls -l
|means that for an executable it will run as the owner of the file, and
|the setgid bit means for an executable it will run under the gid of
|the file, and for a directory means that new files created in that
|directory will be created with the gid of the directory.

Under SunOS the sticky bit for a directory means that files in that
directory can only be deleted or renamed by their owners.  -David-
