This is not really FreeNAS on Debian. Its ooooooold "FreeNAS" with maybe 30-40% of the features and less stability. There's no reason to want this when FreeNAS is free and a lot better.
Thanks. I posted this specifically to get such critiques of these various flavors of FreeNAS: FreeNAS, NAS4Free, OpenMediaVault.
I would really only recommend the official FreeNAS frankly.
