i'm just moved to linux world in ubuntu 10.10. i'm using it for normal life, internet and social networks, multimedia enterainement like musics and movie, a bit of coding with c and python..
i've just learned something about run levels and about init and service command line tools. i understand they are powerful tools and contribute to set up the architecture and a solid base of the entire system. (is this an antiquate model? possible evolutions? alternative models?)
but i don't undesrtand how they can cross my normal life and where i can use it, if i have to learn about it in a deep way or if a can only know that they exists but probabilly i will never touch them.
