gereal - how to painlessly access serial consoles

Serial consoles are still a big thing to access servers, network devices, embedded devices, Raspberry Pis and many other computers. There is a myriad of methods available to access those serial consoles from Linux.

gereal is a new method to access serial consoles using screen in a comfortable way. The main extraordinary feature is that the session automatically opens during system boot and that users can attach to a running session. Attaching to a running session allows one to see what the device has printed on its serial console before the session was attached to, and one can even scroll back in the console history.

gereal makes use of systemd generators. Time permitting, I’m going to give an introduction to using systemd generators as well.
