    Взято с http://wiki.opennet.ru думаю будет полезно
    Установка FreeBSD с Flash
    Ниже скрипт для преобразования установочного iso образа в формат для заливки на USB Flash (в BIOS поставить загрузку с USB-HDD):
    Code:
    #!/bin/sh
    
    # You can set some variables here. Edit them to fit your needs.
    
    # Set serial variable to 0 if you don't want serial console at all,
    # 1 if you want comconsole and 2 if you want comconsole and vidconsole
    serial=0
    
    set -u
    
    if [ $# -lt 2 ]; then
        echo "Usage: $0 source-iso-path output-img-path"
        exit 1
    fi
    
    isoimage=$1; shift
    imgoutfile=$1; shift
    
    export tmpdir=$(mktemp -d -t fbsdmount)
    # Temp file and directory to be used later
    export tmpfile=$(mktemp -t bsdmount)
    
    export isodev=$(mdconfig -a -t vnode -f ${isoimage})
    
    echo "#### Building bootable UFS image ####"
    
    ISOSIZE=$(du -k ${isoimage} | awk '{print $1}')
    SECTS=$((($ISOSIZE + ($ISOSIZE/5))*2))
    
    # Root partition size
    
    echo "Initializing image..."
    dd if=/dev/zero of=${imgoutfile} count=${SECTS}
    ls -l ${imgoutfile}
    export imgdev=$(mdconfig -a -t vnode -f ${imgoutfile})
    
    bsdlabel -w -B ${imgdev}
    newfs -O1 /dev/${imgdev}a
    
    mkdir -p ${tmpdir}/iso ${tmpdir}/img
    
    mount -t cd9660 /dev/${isodev} ${tmpdir}/iso
    mount /dev/${imgdev}a ${tmpdir}/img
    
    echo "Copying files to the image..."
    ( cd ${tmpdir}/iso && find . -print -depth | cpio -dump ${tmpdir}/img )
    #bzcat ${tmpdir}/iso/dist/root.dist.bz2 | mtree -PUr -p ${tmpdir}/img 2>&1 > /dev/null
    
    #echo "/dev/ufs/${UFS_LABEL} / ufs ro 1 1" > ${tmpdir}/img/etc/fstab
    
    if [ ${serial} -eq 2 ]; then
            echo "-D" > ${tmpdir}/img/boot.config
            echo 'console="comconsole, vidconsole"' >> ${tmpdir}/img/boot/loader.conf
    elif [ ${serial} -eq 1 ]; then
            echo "-h" > ${tmpdir}/img/boot.config
            echo 'console="comconsole"' >> ${tmpdir}/img/boot/loader.conf
    fi
    
    cleanup() {
        umount ${tmpdir}/iso
        mdconfig -d -u ${isodev}
        umount ${tmpdir}/img
        mdconfig -d -u ${imgdev}
        rm -rf ${tmpdir} ${tmpfile}
    }
    
    cleanup
    
    ls -lh ${imgoutfile}

    Скрипт для форматирования и монтирования загрузочной USB Flash (Взят с сайта [frenzy])
    Code:
    #!/bin/sh
    
    DEF_DEV=/dev/da0
    
    echo -n "Введите имя устройства USB Flash [${DEF_DEV}]: "
    read DEVICE
    
    if [ -z "${DEVICE}" ]; then
            DEVICE=$DEF_DEV
    fi
    
    if [ ! -c "${DEVICE}" ]; then
            echo "Не найден ${DEVICE}, проверьте путь"
            exit 1;
    fi
    
    dd if=/dev/zero of=${DEVICE} bs=512 count=32
    fdisk -BI ${DEVICE}
    dd if=/dev/zero of=${DEVICE}s1 bs=512 count=32
    bsdlabel -w -B ${DEVICE}s1
    bsdlabel ${DEVICE}s1 >> tmp.$$
    ed tmp.$$ <<EOF
    /a:
    s/unused/4.2BSD
    wq
    EOF
    bsdlabel -R ${DEVICE}s1 tmp.$$
    rm tmp.$$
    newfs ${DEVICE}s1a
    
    TEMPDIR=$PWD/tmpdir.$$
    mkdir $TEMPDIR
    mount ${DEVICE}s1a $TEMPDIR
