Trying to mount root from zfs:zroot []... Enter full pathname of shell or RETURN for /bin/sh: Cannot read termcap database; using dumb terminal settings. # zfs set readonly=off zroot internal error: pInvalid argumentid 19 (zfs), uid 0: exited on signal 6 Abort trap I guess, I could multiuser the box on old kernel and installworld from multiuser, but this could lead to disaster. I see no indication of ABI breakage of this kind in UPDATING, so ... any ideas? sean
