Boot Deploy

boot-deploy is a distro-agnostic script for finalizing and deploying files related to booting Linux on mobile devices. It's used extensively by postmarketOS for all supported devices, but was split off into a separate project to allow other distributions to utilize it too.

Configuration

deviceinfo

boot-deploy uses the "deviceinfo" format from postmarketOS, which is specified here on the postmarketOS wiki.

The deviceinfo file is sourced by boot-deploy, providing configuration at runtime.

Note: not all of the variables on the deviceinfo reference wiki page are used by boot-deploy, some of them are used internally by postmarketOS. For an up to date list of variables that boot-deploy can use at runtime, see the top of the boot-deploy-functions.sh file.

OS-level Customization

boot-deploy requires a file at /usr/share/boot-deploy/os-customization, which is used to provide OS distribution customization for some aspects of its output. This file is sourced in shell script, so it must be in var=value format. It must contain the following variables (the given values are just examples):

distro_name="postmarketOS"
distro_prefix="pmos"
crypttab_entry="root"

Usage

Usage:
	./boot-deploy -i <file> -k <file> -d <path> [-o <path>] [files...]
Where:
	-i  filename of the initfs in the input directory
	-k  filename of the kernel in the input directory
	-d  path to directory containing input initfs, kernel
	-o  path to output directory {default: /boot}
	-c  path to deviceinfo {default: both /usr/share/deviceinfo/deviceinfo and /etc/deviceinfo are sourced, in that order }

		Additional files listed are copied from the input directory into the output directory as-is

The script implementation is found in boot_deploy_functions.sh, which it looks for under /usr/share/boot-deploy/boot_deploy_functions.sh. The default location can be overridden, e.g. for testing purposes, by setting the environment variable BOOT_DEPLOY_FUNCTIONS.
