Linux from scratch
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:

Standing up an enterprise level kube cluster is a 400-500k / year job and not for the faint of heart. It's like telling someone "just learn c". Yes containers are big business but the curve can be steep.
Also op asked for a Linux job...not sure where you made the leap to kube or the ", industry" you're talking about.
If op wants to use Linux they should learn sles and rhel and rocky Linux, their differences in functionality and networking tools and apply for an admin job imo.
Ha! In what currency? Because it sure as hell isn't dollars. Average senior level positions are in the high 100 to low 200k range.
Also, OP is talking about LFS.. No one is going to ask them to do that shit either. All of this is a learning exercise. I didn't say anything about an enterprise level anything. Standing up a cluster is a learning exercise.
Old school admin jobs are drying up extremely fast. The job market and a MASSIVE amount of development effort is going into the kube ecosystem. If you resist this change, you're just going to fall behind.
In usd, yes. K8s experts in the right areas can make 400k plus designing k8s clusters, yes I've seen it. Maybe not that high admining them.
Maybe for you clusters are a learning exercise. For enterprise level business they are standard fare and big business/ money.
Linux admin jobs are everywhere, lol what are you talking about.
I've literally had recruiters drooling over me because I knew what top did and could find my way through a Linux file system.
