The problem observed in my setup is, that after booting the kernel from top of main, there is no such thing as "working kernel" any more, i.e. the damage seems to be permanent. > Also on my side typing '?' at mountroot listed the zfs pool so if it's > the same for you that might be the same problem as mine (of course > selecting the pool at mountroot didn't worked). I tried all partitions listed with "?", but none worked. For the time being I had to reinstall the system with UFS.
