What’s the status of this feature? Functional as per documentation?
Installed package serial-console-enable in VirtualBox and saw the following warning during installation.
Warning: Requested serial terminal but GRUB_SERIAL_COMMAND is unspecified. Default parameters will be used.
Note: this is most likely not a VirtualBox specific warning.
What’s this warning about? Can we, should we fix it?
Default parameters will be used.
What are the default parameters? Are these safe? I.e. could non-root users gain root through use of the serial console?
Quote GNU GRUB Manual 2.12
‘GRUB_SERIAL_COMMAND’
A command to configure the serial port when using the serial console. See serial. Defaults to ‘serial’.
Looks like serial console could work from grub boot menu too. Pretty cool. Could you try please?
