4. 创建用户

sudo chroot ubuntu_rootfs

useradd -G sudo -m -s /bin/bash dolphin
passwd dolphin
passwd root

exit

3. 制作rootfs镜像

#!/bin/bash -e

# Directory contains the target rootfs
TARGET_ROOTFS_DIR="ubuntu_rootfs"
ROOTFSIMAGE=ubuntu-rootfs.img
MOUNTPOINT=./rootfs
OUT=../out
#sudo ./mk-img.sh


#sudo umount $TARGET_ROOTFS_DIR/dev

echo -e "\033[36m Making rootfs \033[0m"
if [ -e ${ROOTFSIMAGE} ]; then
    echo -e "\033[36m Del existing rootfsfile! \033[0m"
    rm ${ROOTFSIMAGE}
fi

if [ -e ${MOUNTPOINT} ]; then 
    echo -e "\033[36m Del existing mountpoint! \033[0m"
    rm -r ${MOUNTPOINT}
fi
mkdir ${MOUNTPOINT}

dd if=/dev/zero of=${ROOTFSIMAGE} bs=1M count=0 seek=4000
finish() {
    sudo umount ${MOUNTPOINT} || true
    echo -e "\e[31m MAKE ROOTFS FAILED.\e[0m"
    exit -1
}
echo -e "\033[36m Format rootfs to ext4 \033[0m"
mkfs.ext4 ${ROOTFSIMAGE}

echo -e "\033[36m Mount rootfs to ${MOUNTPOINT} \033[0m"
sudo mount  ${ROOTFSIMAGE} ${MOUNTPOINT}
trap finish ERR

echo -e "\033[36m Copy rootfs to ${MOUNTPOINT} \033[0m"
sudo cp -rfp ${TARGET_ROOTFS_DIR}/*  ${MOUNTPOINT}

echo -e "\033[36m Umount rootfs \033[0m"
sudo umount ${MOUNTPOINT}

echo -e "\033[36m Rootfs Image: ${ROOTFSIMAGE} \033[0m"
e2fsck -p -f ${ROOTFSIMAGE}
resize2fs -M ${ROOTFSIMAGE}

echo -e "\033[36m Rootfs Finished as ${ROOTFSIMAGE} \033[0m"

4. 将用户添加到组

usermod -a -G video root
sudo usermod -a -G audio root
sudo usermod -a -G video dolphin
sudo usermod -a -G audio dolphin
