How to make emacs display the warning messages which appear on tty1

I live in Emacs; therefore I'd like important warnings and messages 
which in my distribution (Guix System) sends to tty1 be instead caught 
by emacs and displayed in the echo area. I suppose Guix has a list of 
outputs for such messages (I suspect it be tty, tty12 and the log file) 
and I would like instead it be something like 
Emacs-messages-from-Shepherd, and emacs be ready to display whatever 
come in through there. But I wouldn't want emacs to retrieve stuff that 
appears on tty1, I'd like such messages to go directly into emacs. 
Ideas?
