From: george on 11 Jan 2010 09:04 does the old technique of booting of cdrom, mounting the root partition and editing the shadow file still work ? I don't know how to mount the root partion of a zfs filesystem. I'm zfs illiterate. George

Once booted run zfs list You will see your root filesystem in the rpool rpool 13.0G 54.0G 93K none rpool/ROOT 6.50G 54.0G 18K legacy rpool/ROOT/cmroot 6.50G 54.0G 6.39G / rpool/ROOT/cmroot/var 109M 54.0G 109M /var rpool/ROOT/cmroot in this case is the root filesystem all you need to do to mount it is run zfs set mountpoint=/a rpool/ROOT/cmroot then vi /a/etc/shadow and revert the mountpoint back to / zfs set mountpoint=/ rpool/ROOT/ cmroot You may need to run zfs mount rpool/ROOT/cmroot after changing the mountpoint.
