Probably an rc.d script with BEFORE: root that invokes the fsck
command - something along the lines of the following (as yet untested
and missing error checking etc.):

#!/bin/sh
#

# PROVIDE: fsck_ufs
# BEFORE: root
# REQUIRE: fsck
# KEYWORD: nojail

. /etc/rc.subr

name="fsck_ufs"
desc="fsck UFS filesystems for FreeBSD-SA-19:10.ufs"
start_cmd="fsck_ufs_start"
stop_cmd=":"

fsck_ufs_start()
{
        fsck -t ufs -f -p -T ufs:-z
}

load_rc_config $name
run_rc_command "$1"
