  For those that want to see full source bootstrapped, deterministic, and container native alternative to buildroot check out https://codeberg.org/stagex

  Can make a bootable OS with just a containerfile, for example:

  Coincidentally I tried this recently. I dunno if I liked it. It uses the kernel's `make menuconfig` system which seems like it occupies a bad place between "easy usable GUI" and "robust config file you can check in to git".

  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.

  Me: I couldn't write anything longer than 20 lines in make - there's just one type (string), no debugger, no data structures, no standard library, and not even modules.

  Buildroot developers: let's write a build system in make!

  How are kernel or application updates applied to buildroot-installed systems?

  We’ve built something that goes well with buildroot for installing and updating apps during development or in production.

  Does not require cloud or internet access.
