I guess no one liked that idea?
How about at least making sure that the real console gets a message that something is on the bootconsole? Right now the switch message:
console handover:boot [early_shadow0] -> real [ttyBF0]
only is printed on the bootconsole, not on the real console - so someone looking at the real console may not know there is anything on the boot console. They just think that things are missing...
