    Why the dd if you're trying to ufsrestore?

    Now that you've newfsed, mount the root slice.

    # mount /dev/dsk/c0t0d0s0 /a
    # cd /a
    # ufsrestore rf /dev/rmt/0cbn
     (wait for restore)

    At this point you can examine the old /etc/vfstab (which you should keep
    a copy of elsewhere to aid in "by hand" restores) to see which slices
    had what other filesystems. Unless Amanda has given it to you, you'll
    need to figure out which other filesystems are where on the tape. You
    can use 'ufsrestore -i' and then give the "what" command to see which
    filesystem is there. When you know, rewind to that file and do the
    restore...

    # mount /dev/dsk/c0t0d0s5 /a/usr (only an example)
    # cd /a/usr
    # ufsrestore rf /dev/rmt/0cbn
