I want to replace the /etc/network/interfaces file on the resulting image root file system, so I added a bbappend recipe in my meta-rpilinux directory.
The bbappend file looks like this:
And the interfaces file in that directory looks like this:
After I build my image and look in the work build directory for the init-ifupdown package, I see the correct interfaces file :
However, after I burn the image to the SD card with this :
I see the "wrong/original" file in etc/network:
I am fairly new to Yocto and poky, is it possible that another layer/recipe is overriding the interfaces file ?
Note that in my local.conf, I am adding openssh recipe with this :
