Description

The cmdline determines a good bunch of things, such as finding the initrd and where console output goes.

Those are crucial to understand to avoid blank screens and frustration.
Try asking a search engine or forum "why is my screen blank" - it is hard to figure out.

`console=ttyS0` is common, though some platforms, e.g. som Arm based ones, may require a driver specific tty, such as `ttyAMA0`.
