Linux supports multiple consoles listed in the kernel command line. Most messages are multiplexed to all consoles, but the last one specified on the command line is used when writing to /dev/console.

Currently we have console=%s,115200n8 console=tty0. This means that some messages will only show up on the VGA console. We want the VGA console to always be present, but we want the default to be the one specified by cnapi. To ensure that the console specified by cnapi is used for messages to /dev/console, this should be reversed to console=tty0 console=%s,115200n8

I currently have a CN I'm working through a boot issue with, and the live-bottom scripts only output to the VGA console. It'd be a lot easier for me if they were going to the serial console. I'll grab the jenkins build and install it then on my next pass that script output should be on serial.

OK, confirmed, live-bottom script output is now going to the serial, as specified in CNAPI.
