[yocto] recipe removing (some)contents of /etc

> What image are you building?

it is a Freescale iMX6 target, the image name is exactly a fsl-image-qt5 with a playground layer

My understanding these are the preferred options

> > > IMAGE_INSTALL_append = “ canlogger”

But would this still do? (just for my self-learning)

I have other recipes(not *.bbappend) which end up in the image without adding any explicit statement, just the fact of being part of the layer includes them, is there any explanation?

I am still missing something to get the whole picture...

Thanks a lot for the detailed explanations
best Regards
