#!/bin/bash
# This script allows you to chroot ("work on")
# the raspbian sd card as if it's the raspberry pi
# on your Ubuntu desktop/laptop
# just much faster and more convenient
# credits: https://gist.github.com/jkullick/9b02c2061fbdf4a6c4e8a78f1312a689
# make sure you have issued
# (sudo) apt install qemu qemu-user-static binfmt-support
# Write the raspbian image onto the sd card,
# boot the pi with the card once
# so it expands the fs automatically
# then plug back to your laptop/desktop
# and chroot to it with this script.
# Invoke:
# (sudo) ./chroot-to-pi.sh /dev/sdb
# assuming /dev/sdb is your sd-card
# if you don't know, when you plug the card in, type:
# dmesg | tail -n30
# Note: If you have an image file instead of the sd card,
# you will need to issue
# (sudo) apt install kpartx
# (sudo) kpartx -v -a 2017-11-29-raspbian-stretch-lite.img
# then
# (sudo) ./chroot-to-pi.sh /dev/mapper/loop0p
# With the vanilla image, you have very little space to work on
# I have not figured out a reliable way to resize it
# Something like this should work, but it didn't in my experience
# https://gist.github.com/htruong/0271d84ae81ee1d301293d126a5ad716
# so it's better just to let the pi resize the partitions
# shellcheck source=/dev/null # Deactivate SC1090
# shellcheck disable=SC2015 # Deactivating bool hint
