Hi, to solve this one (for the archives maybe): root@vm:~ # zpool import -N newpool root@vm:~ # zfs set mountpoint=3D/ newpool/ROOT/default zfs set mountpoint=3Dnone newpool/ROOT zfs set mountpoint=3D/tmp newpool/tmp zfs set mountpoint=3D/usr newpool/usr zfs set mountpoint=3D/var newpool/var reboot Machine now starts like a charm with the new pool. Amazing. Thanks for all your help guys, this is very much appreciated.
