Linux Kernel Module Cheat

Take the command described at TTY and try adding the following:

-e 'console=tty7': boot messages still show on /dev/tty1 (TODO how to change that?), but we don’t get a shell at the end of boot there.

Instead, the shell appears on /dev/tty7.
-e 'console=tty2' like /dev/tty7, but /dev/tty2 is broken, because we have two shells there:
- one due to the ::respawn:-/bin/sh entry which uses whatever console points to
- another one due to the tty2::respawn:/sbin/getty entry we added
-e 'console=ttyS0' much like tty2, but messages show only on serial, and the terminal is broken due to having multiple shells on it
-e 'console=tty1 console=ttyS0': boot messages show on both tty1 and ttyS0, but only S0 gets a shell because it came last
