I can't get that to work on i386.  Here is /etc/rc.d/fsck:
____________________________________
        fi

        echo "Ready for tunefs"
        /sbin/tunefs -j disable /dev/da0p2
}

load_rc_config $name
run_rc_command "$1"

____________________________________


reboot computer and here is the output from messages:

____________________________________


Nov  4 14:07:19 Router kernel: Ready for tunefs
Nov  4 14:07:19 Router kernel: Clearing journal flags from inode 4
Nov  4 14:07:19 Router kernel: tunefs: soft updates journaling cleared but soft updates still set.
Nov  4 14:07:19 Router kernel: tunefs: remove .sujournal to reclaim space
Nov  4 14:07:19 Router kernel: Mounting local file systems:.

and the output from mount:

Router# mount
/dev/da0p2 on / (ufs, local, journaled soft-updates)
devfs on /dev (devfs, local, multilabel)

____________________________________

Journaled is still on after 2 reboots.

Router# uname -a
