If the motherboard is configured to redirect the output onto a different COM port, or if the operator prefers to have foreground messages over serial instead of VGA/iKVM, they have to override GRUB_CMDLINE_LINUX_DEFAULT via grub-config-flags.
This could be made more user-friendly by providing new config options. For example:
console-serial-port:
default: ""
type: string
description: |
Console output can be redirected to a serial port.
Specify which one here, using either the ttyS
device name or a COM port.
COM ports will be converted to tty device names
as follows: COM1 = ttyS0, COM2 = ttyS1, etc.
foreground-console:
default: "vga"
type: string
description: |
Output foreground messages on either vga or serial.
NOTE: "vga" includes iKVM virtual consoles found on
the BMC web UIs
Valid options: [vga|serial]

The charm sets the following GRUB_CMDLINE by default:
GRUB_CMDLINE_LINUX_DEFAULT="$GRUB_CMDLINE_LINUX_DEFAULT console=tty0 console=ttyS0,115200 console=ttyS1,115200"
