kiss VS buildroot

For something that's more of a prepackaged build-your-own-Linux kit, KISS Linux[0] is also interesting. It's kind of a microdistro with minimal abstraction over the raw guts, and "packages" are just pre-downloaded source code repos that you compile yourself.

The "package manager" is just a shell script. The installation process[1] is entirely manual, so you control every step as you bootstrap up to building your own kernel and installing each subsystem all the way up to compiling and running Firefox. It's pretty neat.

A good Bash code to read is some projects from GH user dylanaraps a creator of neofetch and KISS Linux (kiss is a package manager written in POSIX sh) another repo to explore is bashbox (forked from dylanaraps/bareutils) A coreutils written in pure bash.

See KISS for examples - this is a real desktop system used by some people (including me... hopefully)

I did it few times. It's so much easier nowadays with https://buildroot.org/

If you dig through the rootfs of the K1 it becomes clear that Creality is using buildroot so we should be able to do that ourselves - at least some of us.

An embedded system like Roku doesn't need to "run everything", it just needs to run their "platform", which is probably quite small. It's pretty trivial to assemble your own OS from "off-the-shelf" components. You can use something like buildroot to spin up a new OS in half a day, using only the components you want. You can also use "smaller" components that have far fewer features, meaning less bugs and less updates.

> I do this for every Windows installation that is used for similar purposes, like embedded machines that has to run a single application, virtual machines, etc.

Have you tried running Linux for these use cases? This sort of thing is an area Linux excels, in my experience.

When you run Windows, you're in for the whole kit and caboodle. Most of the components are proprietary, closed-source black boxes. You can only poke and prod and test and hope things don't break in unexpected ways.

Conversely, Linux can be easy stripped down to a bare bones kernel and a single statically-linked binary. I can run a useful application on top of Linux with the whole system weighing in smaller than bootmgfw.efi.

Something more complex, but still custom, is easily crafted with Buildroot.

Have a look at the commit history of Linux or buildroot for nice readable commit histories.

Gentoo could teach you more about what is involved in dependency handling and actual ‘construction’ of a Linux system. But Linux From Scratch is a much better teaching tool for learning this, and even things like Buildroot are arguably better than Gentoo for this because they generally force you to care about a lot of the stuff that Gentoo hides away to make the system nicer to use.
