Re: [meta-raspberrypi][PATCH] Add networkd as default for RaspberryPi

[Herve Jourdain <herve.jourdain@neuf.fr>]

Indeed, it's a valid point, and I should probably be more cautious in the naming of the bbappend.
This said, I - maybe wrongfully - assumed that anyone including the meta-raspberrypi layer would actually want to run on a raspberrypi, which does have an Ethernet interface I believe on all machines - I only have a RaspberryPi 2, so I didn't check all other devices, so might assumption might be wrong there.
Is there any version of raspberrypi without an Ethernet interface?

BR,

Herve

Please don't modify these kind of settings in a BSP. Even worse by doing it as suggested all machines will get this modification. This for sake that you have no network. Why not add networkmanager or whatever and being fine?
