Build Ubuntu 22.04(Console) RootFS

Setup parameters

shell$ apt-get install qemu-user-static debootstrap binfmt-support
shell$ export targetdir=ubuntu22.04-console-rootfs
shell$ export distro=jammy

Build ubuntu22.04-console-rootfs with QEMU

Build the root file system in $targetdir(=ubuntu22.04-console-rootfs)

shell$ mkdir                                               $PWD/$targetdir
shell$ sudo debootstrap --arch=arm64 --foreign $distro     $PWD/$targetdir
shell$ sudo cp /usr/bin/qemu-aarch64-static                $PWD/$targetdir/usr/bin
shell$ sudo cp /etc/resolv.conf                            $PWD/$targetdir/etc
shell$ sudo cp scripts/build-ubuntu22.04-console-rootfs.sh $PWD/$targetdir

shell$ sudo mount -vt proc proc                            $PWD/$targetdir/proc
shell$ sudo mount -vt devpts devpts -o gid=5,mode=620      $PWD/$targetdir/dev/pts

Change Root to ubuntu22.04

shell$ sudo chroot $PWD/$targetdir

There are two ways

  1. run build-ubuntu22.04-console-rootfs.sh (easy)
  2. run this chapter step-by-step (annoying)
