Mobile NixOS

An overlay for building stuff.

This is a work-in-progress.

WIP notes

nix-build --argstr device asus-z00t -A all
# Maybe `nix copy ./result --to ssh://another-host`
adb wait-for-device && adb reboot bootloader
fastboot boot result # or full path
# getting adb and fastboot working is left as an exercise to the reader.

Alternatively, helpers under bin can be used. They mostly pave over the nix CLI to provide one-liners and one-parameter helpers.

# Builds -A all for device_name $1
bin/build asus-z00t

Booting qemu

bin/build qemu-x86_64
bin/boot-qemu

This currently does not build using 18.03 and may never (18.09 may release before!)

`local.nix`

This file can be used to override (possibly with lib.mkForce) options on a global scale for your local builds.

If the file does not exist, it will not fail.

A sample local.nix:

{ lib, ... }:

{
  mobile.boot.stage-1.splash.enable = false;
}

This will disable splash screens.

This will be most useful to configure local sensitive stuff like password (hashes) or ssh keys.

Goals

The goal is to get a nix-built operating system, preferably NixOS running on mobile devices, e.g. Android phones.

This is intended as building blocks, allowing the end-users to configure their systems as desired.

The amount of targeted devices does not dilute or devalue the work. It's the other way around, it increases the odds that people will start using the project and contribute back.

Prior work

This project initially borrowed and relied on the hard work from the PostmarketOS project. They are forever thanked in their valiant efforts.
