Boot issues with custom rootfs

Hi,

I want to create a custom rootfs which only contains a small number of packages. Therefore I created the following scripts, which download the ubuntu-base image and installs some necessary packages using qemu:

  then echo "Please run as root"
  exit
fi

After generating the rootfs, I executed the apply_binaries.sh script and flashed the board using flash.sh. The board is booting but some services fail to start during boot process. Nevertheless, the login prompt becomes visible. Unfortunately, the keyboard is not working, so I was not able to log in. Therefore I tried to see what happens by connecting with the serial console. Unfortunately, the output stops early when booting the kernel:
