GNU/Linux is the UNIX-like open-source operating system the world runs on.

I had my first contact with GNU/Linux as a desktop user in 2008. Since then, I have daily-driven Ubuntu, Linux Mint, Windows (!), Manjaro and Arch Linux (btw). I have also used Rocky Linux on servers at work. Since more than two years, I own a small homelab that runs a couple of services for my own use. An interesting constraint is that it is 2000km away from me, so I am forced to handle it with care and architecture it in a resilient manner.

All this led me to slowly gaining an intuitive understanding of the operating's sytem architecture over the years. By now, after having been exposed to a great deal of the userland system components and kernel subsystems to varying degrees, I have a strong working knowledge and can debug my way out of most problems.

My next goal is to get ahold structured formal knowledge to accelerate my learning of Kernel interfaces, subsystems and internals.
