Hi,

I need to update kernel bootargs basically add (quiet net.ifnames=0 biosdevname=0). I checked grub-mender-grubenv and grub configuration scripts are fetched from [repo](https://github.com/mendersoftware/grub-mender-grubenv/blob/master) then build. Can I easily override it in bbappend or is there other way how to do it. I would suggest to add some optional yocto variable to have possibility for modifications. Thanks.

`bbappend` is the currently available approach.

This has been discussed once before,

[https://groups.google.com/a/lists.mender.io/forum/#!searchin/mender/bootargs|sort:date/mender/5d3TuX5DVQA/e4eqZ0k8CAAJ](https://groups.google.com/a/lists.mender.io/forum/#!searchin/mender/bootargs%7Csort:date/mender/5d3TuX5DVQA/e4eqZ0k8CAAJ)

The idea of providing a variable for `bootargs` would make sense to me as this is a very common thing to change.
