When will NBU support Domino 9.0 on Red Hat Linux?

I am aware the NBU team is slowly adding support for IBM Domino 9.0.  It is now supported on Windows 2008 and 2013, as well as SLES and AIX.  My question is if anybody knows when NBU will support Domino 9.0 on Red Hat Linux? IBM Domino 9.0 was released a year ago.  This is quite an urgent matter for us.

Thanks!
