[HOW-TO] chrooting into ARM enviorment.

Chrooting into ARM filesystem can be really useful in order to quickly compile stuff, installing packages, repairing Boot.
But in order to get that to work you need two tools:
Code: Select all
qemu-user-static - enables you to execute binaries that were compiled to other architectures
Proot - chrooting tool with various features, including qemu static execution

You can get these for Arch Linux from AUR
Code: Select all
packer -S proot qemu-user-static


once you installed both you can mount you arm filesystem by

Code: Select all
mkdir mnt
mount /dev/sdb1 mnt
cd mnt
cp /usr/bin/qemu-arm-static usr/bin # qemu-arm-static is for armv7, you can use also qemu-aarch64-static and qemu-armeb-static
#it will copy the right qemu executable required to emulate these binaries to the local usr/bin
proot -R . -q qemu-arm-static # will enter the chroot environment
uname -m # will help you determine if you entered chroot environment successfully.


once you are inside you are free to do as you please, you can access the host filesystem in /host-rootfs .

and you should edit /etc/resolv.conf and enter a DNS address or you won't be able to resolve DNS addresses at all.
