Hi guys, my face is red.
I bungled the fix to /etc/ttys in that update (and no, it's not fixed yet - I'm doing that right now). The path to zfsd should be /sbin/zfsd - it got moved into a system location from /usr/local and I forgot to track that change in /etc/ttys. No idea why it didn't show up in my console log last night, but it shows up this morning, and I've already fixed it. New update on the way now (containing just this fix).
