  1. Tải xuống và giải nén kho lưu trữ đã chuẩn bị
cd /opt
wget -c -O debian_stretch-9.2-armhf_clean.tgz https://bit.ly/2LFoL0G
tar -xvzf ./debian_stretch-9.2-armhf_clean.tgz
  1. Tạo file khởi động cho các dịch vụ đã cài đặt
cat >> /opt/etc/init.d/S99debian << 'EOF'

Nhấn ENTER để tạo file

  1. Làm cho tập lệnh có thể thực thi được
chmod 755 /opt/etc/init.d/S99debian
  1. Tạo liên kết tượng trưng đến các dịch vụ start-stop hoặc vào debian dễ dàng hơn
touch /opt/etc/chroot-services.list
ln -s /opt/etc/init.d/S99debian /opt/bin/debian

Chúng ta dễ dàng chạy, vào, thoát, dừng debian thông qua các lệnh

debian start
debian stop
debian restart
debian enter
debian status
  1. Copy file host
cp /etc/hosts /opt/debian/etc/
dpkg-reconfigure tzdata
aptitude install locales
dpkg-reconfigure locales
