Agetty resets the terminal prior to the username login prompt in the
termio_init(tp, speed, op) function. I am wondering if it makes sense
to add command line options to setup the initial terminal (opost, onlcr,
onlret, etc.). If the terminal sits at the login prompt and messages
are displayed to the console those messages will eventually shift to the
right edge of the screen and become incoherent. Below is a diff showing
the simple change (not saying this is correct because it probably should
allow user input). Is there a reason why agetty does not allow onlcr
during the login prompt?
