All went fairly well and the system will boot but fails to mount the root file system and dumps me a the mountroot> prompt. Entering zfs:zrootusb at the prompt works and the system finishes booting. In /boot/loader.conf I've got: zfs_load="YES" vfs.root.mountfrom="zfs:zrootusb" zrootusb mountpoint is set to legacy and /etc/fstab exists but is empty, per the guide. Any ideas? Thanks, Carl
