The whole "battle" with you rised due to "is/was" and I spelled it wrong - ZFS was developed on Solaris (was exclusive).
Everywhere I said "ZFS is Solaris exclusive" I referred to its legacy, NOT that one can use ZFS only on Solaris(!).
Again check my first post as response to first comment.
I have nothing against.
I am not ZFS user, so I can't help, except on my own. Can do this if everyone denies, because I too have a bit interest.
But remember, "port" or not, my sentence had different meaning! We drift too much in meaningless direction.
I don't care if its port or not, seriously. I am against stupidity as in 1st post in this thread - regardless of OS.
I know that both are opensource and I don't care about licenses, because I am not developing them.
My problem is that ZFS license caused integration type like installing proprietary Nvidia driver. :/
