--------------------------------------
Jakob, release notes sounds much scarier than it should be. Just selecting an
incompatible flag is enough, I think.

> 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.
