When booting Debian, you'll see it printing a lot of information about the system variables and such.

I don't really need to see all that, so I'd like to modify some scripts to make sure that on boot, it just does what it has to do, without printing it on the screen. Just something I fancy.

Offcourse, still seeing errors would be nice. But that long slur of text, I could do without.

I've tried looking it up, but I can't find documentation on this specific thing anywhere.
