The Linux Kernel Startup

Have you ever wondered what really happens between the moment you press the power button and the moment your login screen shows up? That gap—usually some seconds—hides one of the most intricate initialization sequences in computing. Today I want to walk you through it. This is the first article in a series where I’ll try to make sense of the Linux kernel internals together with you. We’ll talk about how Linux boots, how it manages processes and memory, how it deals with hardware, and so on. If you’ve ever been curious about what’s happening under the hood, you’re in the right place.
