This was straightforward in System V, but systemd makes it a bit more complex. However, it has its own timers. What are targets? It is often stated that targets serve as an analogy to runlevels in System V init. I fundamentally disagree. There are more of them and they can […]

But today I will not talk about the twists and turns of corporate life, but rather about self-education and the literature that has helped me throughout these years.
