Build Debian11 RootFS

Setup parameters

shell$ apt-get install qemu-user-static debootstrap binfmt-support
shell$ export targetdir=debian11-rootfs
shell$ export distro=bullseye

Build Debian RootFS first-step in $targetdir(=debian11-rootfs)

shell$ mkdir                                               $PWD/$targetdir
shell$ sudo chown root                                     $PWD/$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-debian11-rootfs-with-qemu.sh  $PWD/$targetdir
shell$ sudo cp debian/linux-image-5.15.108-zynqmp-fpga-generic_5.15.108-zynqmp-fpga-generic-5_arm64.deb  $PWD/$targetdir

Build Debian RootFS second-step with QEMU

Change Root to debian11-rootfs

shell$ sudo chroot $PWD/$targetdir

There are two ways

  1. run build-debian11-rootfs-with-qemu.sh (easy)
  2. run this chapter step-by-step (annoying)

Run debootstrap second stage

debian11-rootfs# distro=bullseye
debian11-rootfs# export LANG=C
debian11-rootfs# /debootstrap/debootstrap --second-stage

NOTE

If the version of qemu-user-static is old, you may get the following error.

debian11-rootfs# /debootstrap/debootstrap --second-stage
W: Failure trying to run:  /sbin/ldconfig
W: See //debootstrap/debootstrap.log for details

In this case, please update qemu-user-static. I used 'qemu-user-static_6.1+dfsg-8_amd64.deb'.
