Maybe I skimmed too fast, but I didn't see your criticisms in the write up cited. They're a good critique, ssd aside: ssd are magic, any filesystem.

ZFS mainline kernel aside, is the only FS I've seen which is able to encompass redundancy and is portable BSD <-> Linux. It isn't a big reason I run it, but it's one of them. Snapshotting is the big reason although the various journal fs had this ages ago.

I don't personally feel a zealot, but I admit to proselytising.
