Initial preparation

mkdir root tar -xpf ubuntu-base-<version>-base-arm64.tar.gz -C root cp /usr/bin/qemu-aarch64-static ./root/usr/bin/ cp -b /etc/resolv.conf root/etc/resolv.conf

Create a new script file

vim ch-mount.sh #!/bin/bash function mnt() { echo "MOUNTING" sudo mount -t proc /proc ${2}proc sudo mount -t sysfs /sys ${2}sys sudo mount -o bind /dev ${2}dev sudo chroot ${2} } function umnt() { echo "UNMOUNTING" sudo umount ${2}proc sudo umount ${2}sys sudo umount ${2}dev } if [ "$1" == "-m" ] && [ -n "$2" ] ; then mnt $1 $2 elif [ "$1" == "-u" ] && [ -n "$2" ]; then umnt $1 $2 else echo "" echo "Either 1'st, 2'nd or both parameters were missing" echo "" echo "1'st parameter can be one of these: -m(mount) OR -u(umount)" echo "2'nd parameter is the full path of rootfs directory(with trailing '/')" echo "" echo "For example: ch-mount -m /media/sdcard/" echo "" echo 1st parameter : ${1} echo 2nd parameter : ${2} fi

Configure Filesystem

Enter Filesystem

chmod +x ch-mount.sh
./ch-mount.sh -m root/
chmod -R 777 /tmp
