`zfs list` permission denied

I used to be able to run `zfs list` as an unprivileged user. Now I
can't, even when my user is in the operator group.

==== BEGIN LOG ====
hbsd-current-01[shawn]:/home/shawn $ zfs list
Operation not permitted
hbsd-current-01[shawn]:/home/shawn (1) $ id
uid=1001(shawn) gid=1001(shawn) groups=1001(shawn),0(wheel),5(operator)
hbsd-current-01[shawn]:/home/shawn $ ls -l /dev/zfs
crw-rw-rw-  1 root  operator  0x52 Sep 10 10:43 /dev/zfs
==== END LOG ====

Thanks,
