I have been using Linux as my daily driver for quite some time (around 5-6 years) and usually manage to get whatever needs to be done. However, I now wish to learn it in a more structured manner, which includes understanding utilities and the workings of Linux. What resources should I look out for?
I would look for something interactive e.g LFS but in containers (or VM or WASM VM) with checkpoints with instructions, something risk free yet hands on.
Not for books.
i will add that using something like arch linux is unironically good to get a feel for how it clicks together without doing it all from complete scratch.
despite the usual stability caveats (and please do backups), it is a daily-driveable system you can learn on.
I’m honestly kicking myself for using arch instead of something without systemd.
I used Arch to learn Linux and ended up just learning systemd really well.
you can use many init systems on gentoo and its also good for the purpose!
