And of course, dataset zboot:/ROOT/fist in above example should set as bootfs by #zpool set bootfs=zboot/ROOT/fist zboot and mountpoints of zboot and zboot/ROOT should be set to NONE by #zfs set mountpoint=none zboot #zfs set mountpoint=none zboot/ROOT respectively. Otherwise, boot would fail. When I forgot to set bootfs, got boot failure, even I've set vfs.root.mountfrom in /boot/loader.conf properly. Are these OK? # This is easily forgotten on manual installation. :-< > > > > On 28 April 2016 at 08:44, Eugene M.
