Question

I’m using the grub-UEFI integration of mender that is based on: GitHub - mendersoftware/grub-mender-grubenv.

I would like to add the grub quiet option so that the grub console output will be suppressed or redirected to a serial port. Is there any hidden option to append the quiet option to the kernel boot options? I could not find anything in the bb files of the mender-meta layer.

The desired result is that the boot is without any log message on the screen.
