In this case, the user can just configure that another console in /etc/inittab, as it was done before auto-console patch.

But whether init acts on it or not will be controlled by a second parameter called init.autocon. If init.autocon is not set to 1, then init will ignore the console= kernel parameter. Is that correct? The only potential problem I see with this approach would be if someone wanted the kernel to set up a console on one device and init to set up a console on another device. This seems unlikely, but I wonder if it's possible someone would want to do that? I wouldn't want to introduce a fix that prevents people from having both options if they want it.
