This turned out to be a problem with fuse.ko and not a problem with ZFS. Loading fuse.ko in loader.conf breaks mounting of the root filesystem at boot, at least with ZFS. I haven’t delved any deeper yet since I can fix the problem by not loading fuse.ko in loader.conf.

Subject changed accordingly.
