When last I installed arch, there was a limit in the kernel that couldn't
boot zfs for some reason, but otherwise tried it and liked what I saw. I'm
more interested in encryption+boot if possible, but don't know anyone using
zfs for anything real yet.
I'd like to replace my md+luks+lvm setup with something that can do all
native for raid+encryption+dynamic volumes, just would love to see someone
else doing so already.
