Re: Behaviour of .bbappend when default script is not present

Hi,

You could also consider using the `BBFILES_DYNAMIC`[1] variable, this way your bbappend
would only apply when there is `meta-raspberrypi` in the build configuration. Your bbappend
could be placed in custom layer under
`dynamic-layers/raspberrypi/recipes-bsp/bootfiles/
rpi-cmdline.bbappend` path and than in its
layer.conf file add

BBFILES_DYNAMIC += " \
    raspberrypi:${LAYERDIR}/dynamic-layers/raspberrypi/recipes-*/*/*.bbappend \
"

Looks like the best option to add kernel command parameters is to use `
rpi-cmdline.bbappend`
with dynamic-layers as mentioned above. You should add changes to CMDLINE[2] variable
