Bug#704981: Append console= parameters to Linux kernel conditional on terminal_input interaction

[martin f krafft]

Package: grub-pc
Version: 1.99-27
Severity: wishlist
Tags: upstream

With delight I noticed that grub2 now accepts multiple terminals for
terminal_input and terminal_output and mirrors the menu on all in
real-time. This now let's me put the Grub menu on both, the serial
port and the local console.

Grub then starts the Linux kernel (most of the time anyway) and
passes the following parameters (typically) to the kernel:

  … console=tty0 console=ttyS0,38400n8

Unfortunately, the Linux kernel cannot output everything to two
consoles and the above will have all information from /sbin/init and
/etc/init.d/rc reach only the serial port.

In most cases this is what I want, but when I am sitting at the
console itself, this isn't ideal.

What would be ideal is if Grub only appended the above kernel
parameter unless I interacted with the Grub menu over the console.
If I do that, then it should either switch the two console=
parameters, or just leave it off entirely.

I have looked everywhere, but I don't think this is possible. It
would be really nice, however, if Grub could learn how to do that.
