# 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

|
|
# 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

# 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
