Hi everybody, I’ve been using linux for over 15 years with a huge gap in between. I think i stopped at 14 (Ubuntu) something and started again at 20 something. So i had to learn alot again. Luckily it all came back quick. Now since this week I started linux from scratch to learn more about the way it’s build. I’m also going to get some education to point myself in the direction of a linux job. I just love the way it works. It makes sense to if you now what I mean (which you probably do)
I have two questions. Are there things I should try with LFS after completing my build? And what are some good linux educational sites? I’m currently thinking of the linux foundation. Anyway thanks for reading. Greeting from Belgium! Mr. Nowhereman
Knowing this stuff is fine but make sure to keep your goals in mind. If the idea is to get a job, figuring out how Bluetooth works isn’t going to get you anywhere. You need to move in the direction the wider industry is moving. That direction is running containers in kubernetes.
If you can stand up a kube cluster, write a Prometheus exporter in go, scale pods based on those metrics, and auto resize workloads’ resource requests, then you should be able to find a job without much trouble… These are the things ops people are expected to do in 2023.
EDIT: The CNCF is a great resource for modern tooling.

Valid point. Kubernetes didn’t really grab my attention (yet) Maybe it should.
Kube solves a ton of really complicated problems. I think a big part of the learning curve is just understanding what those problems are/were to know why we are all doing this in the first place.
Rolling out something like Talos is a good starting point for a sandbox to play around in. When I feel like you understand the basic ideas of things that can be run in kube (deployments, cronjobs, services, ingresses, etc) this is a really great resource to level up your understanding:
Some things to check on ur lfs:
- bluetooth audio
- screenshare (with media audio)
- mic quality (sometimes there’s a lot of static sound if not tuned properly)
- try running a game
- try running other resource intensive software like training an ml model or running 3d cad software
- try writing to files that you’re not supposed to be able to (without using sudo), to test that you gave the proper read/write/execute access to system files.
After you do LFS try making a minimal bootable system (on a stick) and see what’s the bare minimum you can put on it to get a working console. Hint: init can be any executable or script, it doesn’t have to be complicated.
You can also add useful tools like
partedand make your own little mini-rescue distro that you can use when something goes wrong with your main system.Haha it’s funny that the massive systemd is just a replacement for a shell script
The Linux Foundation hosts brilliant courses on OS virtualization in Linux - after that there is a pretty clear path at a cloud administrator career.
