This part, though, is really easy nowadays. FreeNAS is idiot friendly.
At some point, I need to migrate my current FreeBSD/ZFS setup to something newer, and I'll probably use FreeNAS next round simply because it's so much easier to manage. (Yes, I can do it from the command line--but I do it so rarely that I always have to go reload all the ZFS command set into my working memory.)
Why didn't you at least do this?
