安裝debootstrap和qemu-user-static：apt install apt-transport-https qemu qemu-user-static binfmt-support debootstrap

構建ubuntu 18.04系統(tǒng)，基礎包為minbase，使用清大的源：qemu-debootstrap --arch arm64 --variant=minbase --include=whiptail,ca-certificates,tzdata bionic rootfs http://mirrors.ustc.edu.cn/ubuntu-ports/

配置軟件源：cat > rootfs/etc/apt/sources.list <

deb http://mirrors.tuna.tsinghua.edu.cn/ubuntu-ports/ bionic main restricted universe multiverse

# deb-src https://mirrors.tuna.tsinghua.edu.cn/ubuntu-ports/ bionic main restricted universe multiverse

deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu-ports/ bionic-updates main restricted universe multiverse

# deb-src https://mirrors.tuna.tsinghua.edu.cn/ubuntu-ports/ bionic-updates main restricted universe multiverse

deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu-ports/ bionic-backports main restricted universe multiverse

# deb-src https://mirrors.tuna.tsinghua.edu.cn/ubuntu-ports/ bionic-backports main restricted universe multiverse

掛載本地設備文件到rootfs：mount -t proc /proc rootfs/proc

mount -t sysfs /sys rootfs/sys

mount -o bind /dev rootfs/dev

mount -o bind /dev/pts rootfs/dev/pts

chroot rootfs內配置：LANG=C.UTF-8 chroot rootfs/ /bin/bash

在rootfs內執(zhí)行：cp /usr/share/zoneinfo/Asia/Shanghai /etc/localtime

apt update

apt upgrade

apt install systemd -y

apt install wireless-regdb crda -y

apt install rsyslog udev dbus kmod openssh-server netplan.io man vim wget net-tools sysstat tmux less wireless-regdb crda dosfstools parted rng-tools -y

echo 'PermitRootLogin yes' >> /etc/ssh/sshd_config

passwd root

umount /dev/pts/ /dev/ /proc/ /sys

exit

為方便使用之前編譯的內核和armbian的uInitrd、firmware文件，掛載armbian的img鏡像到本地：losetup -P -f --show Armbian_5.62_Aml-s9xxx_Ubuntu_bionic_default_4.18.7_20181012.img

mount /dev/loop3p2 /mnt

mount /dev/loop3p2 /mnt/boot

mv /mnt/boot/* rootfs/boot/

mv /mnt/lib/modules/ rootfs/lib/

#也可安裝armbian的firmware-aml-4.18-20181011_5.62_arm64.deb

mv /mnt/lib/firmware/ rootfs/lib/

mv /mnt/etc/modprobe.d/ rootfs/etc/

mv /mnt/etc/fstab rootfs/etc/

mv /mnt/root/install.sh rootfs/root/

將armbain鏡像內的文件全部刪除，將新做的系統(tǒng)移動過去。rm -rf /mnt/*

mv rootfs/boot/* /mnt/boot/

mv rootfs/* /mnt/
