Buildroot
Buildroot is an open-source tool that simplifies embedded Linux system generation via cross-compilation, allowing users to build systems in 15-30 minutes and supporting numerous packages with an accessible structure.
Read original articleBuildroot is an open-source tool designed to simplify the generation of embedded Linux systems through cross-compilation. It efficiently manages the entire process, including the creation of a cross-compilation toolchain, root filesystem, kernel image, and bootloader. The user-friendly configuration interfaces, such as menuconfig, gconfig, and xconfig, allow users to build a basic system in approximately 15-30 minutes. Buildroot supports a wide range of packages, including the X.org stack, Gtk3, Qt 5, GStreamer, Webkit, and Kodi, along with numerous network and system utilities. Its straightforward structure, based on the familiar Makefile language, makes it accessible for users to understand and extend. The project benefits from active contributions from many developers, with ongoing discussions and recent commits reflecting its vibrant community.

Bootstrappable Builds
Bootstrappable builds improve trust and security in computing by minimizing reliance on opaque binaries. Developers are encouraged to adopt best practices and collaborate through community discussions to address bootstrapping challenges.
Can make a bootable OS with just a containerfile, for example:
https://git.distrust.co/public/airgap/src/branch/main/Contai...
https://git.distrust.co/public/enclaveos/src/branch/master/C...
Once you've configured it it then does a lot of downloading and compilation of random stuff and it's all strung together with janky shell scripts which means it's almost guaranteed to break.
I got some weird errors that returned zero google results and the source of the error was a long awful shell pipeline involving `sed`, `tr` etc.
Doesn't scream quality.
I gave up and switched to manually compiling Linux and OpenSBI (which is really all I needed so buildroot was overkill anyway). Went much smoother and I actually vaguely understood what was happening.
I haven't tried Yocto, maybe that is better engineered.
Buildroot developers: let's write a build system in make!
Does not require cloud or internet access.
