Error if no serial interface is present (/dev/ttyS0: not a tty)
Open, WishlistPublicBUG

Description

Not all machines ship a serial interface anymore.

On my ESXi instance I stumbled upon Nov 29 10:34:41 CR1 agetty[12394]: /dev/ttyS0: not a tty in my systems logs b/c I have not specified a serial console.

Also GRUB doesn't like it

We should make VyOS more intelligent to autodetect the serial console or even better, make it configurable. Could be that someone has a serial port but does not want a console?

T117
T169

Looking through the sources, I found ./data/live-build-config/includes.chroot/opt/vyatta/etc/config.boot.default which is the default configuration that will be installed. It holds a serial interface.

console {
    device ttyS0 {
        speed 9600
    }
}
