> Our users (especially Pig) heavily use /tmp for temporary storage. 
> Permission are set to 777.
> However, this means any users can rename and also remove (by moving to .Trash) other users directories and files.
> It would be nice if we can have a sticky bit like unix. 
> Copy&Pasted from manpage.
> STICKY DIRECTORIES
>        When  the  sticky  bit  is set on a directory, files in that directory may be unlinked or renamed only by
>        root or their owner.  Without the sticky bit, anyone able to write to the directory can delete or  rename
>        files.  The sticky bit is commonly found on directories, such as /tmp, that are world-writable.
