custom-rpi-img's Introduction

custom-rpi-img

Requirements

This will only work on linux machines. It will not work on macOS because there's no viable way to mount ext3/4 partitions.

A bootstrap script has been provided. The only setup you will need to do is to initialize git submodules and run the script

git submodule update --init --recursive .
./script/bootstrap

Usage

Building

To build, simply run ./build.sh. This script will do the following:

Download the base raspios image if not already downloaded
Mount raspios
Execute custom scripts/commands
Unmount raspios
Package a new raspios image file and zip it

The final .zip file will be in build/

Running scripts/commands inside the custom raspios image

Place any scripts you want to run inside of src. When a new script is added, make sure it to build.sh under the section that looks like this:

        # Use chroot to run any commands
        # Ex:
        #     sudo chroot "${IMAGE_MOUNT_POINT}" /bin/bash whoami
        sudo chroot "${IMAGE_MOUNT_POINT}" /bin/bash /repo/src/00-test.sh
        sudo chroot "${IMAGE_MOUNT_POINT}" /bin/bash /repo/src/01-my-new-script.sh
