Mac OSX is that their NFSv4 client can use named attributes (with a specific mount option setting). Unfortunately I don't have a Mac.
I am going to try and install Solaris in a bhyve instance. Oracle does allow freebie Solaris licenses for educational purposes, but I'm not sure if I can figure out how to install it in bhyve?
