The default of console\_bootargs seems to be

`"console=tty0,115200n8 console=ttyS0,115200n8 console=ttyO0,115200n8 console=ttyAMA0,115200n8"`

As we do not want any console in our setup, how can we disable it easily in Yocto? Unfortunately there doesn’t seem to be a MENDER\_ variable.

Apparently console settings are set via

`set console_bootargs="console=tty0,115200n8 console=ttyS0,115200n8 console=ttyO0,115200n8 console=ttyAMA0,115200n8"`

in

`01_console_bootargs_grub.cfg`

in the repo

`https://github.com/mendersoftware/grub-mender-grubenv`.

You can make a `grub-mender-grubenv_%.bbappend` and add extra cfg files there. If they follow the same format, `XX_DESCRIPTION_grub.cfg`, where `XX` is two digits, then it will be automatically picked up and executed according to the numbered order. So you can put your own console command at some point later in the execution.
