That's the part I don't understand -- why are the RichACL patches being

Everyone loves the simplicity of mode bits (including me) until you run
into things like the need to automatically create home directories on an
NFS-mounted filesystem or security situations where, for example, you
want users to be able to edit but not delete files, and then you're kind
of stuck listening to your Windows colleagues propose a Storage Spaces
solution.
