I have enabled serial console over null-modem cable in Debian 10 like this:
systemctl enable [email protected].
That was all there was to it. However, while now I can see all the startup messages over serial (initial kernel messages and
systemctl service start messages), nothing is displayed on monitor (virtual tty) until login prompt appears.
Is it possible to have those startup messages displayed on both monitor and over serial connection?
console= twice in the kernel command line.
