What to do about Samba (Windows) support
The immediate concern is that the samba36 port has been removed from the ports tree, and we either need to disable samba support entirely or upgrade to samba4.
As you recall, we use samba to export home/proj dirs to Windows nodes. The bigger issue is whether we are going to continue to support Windows images at all. We only support Windows on the mothership anyway (though there might still be other sites that do it--Deter does, but they don't track us anymore), so maybe we just turn off Windows support?
