Hi Daniel,
thanks for the explanation. To be honest, when I was dealing with the
layer structure, I didn't take a case about the layer outside of "work"
directory.
Basically it's the same as mine, but respect the external layers
outside of work, right? So, your proposal makes sense to me.
layers
├── meta-my-layer
├── meta-openembedded
│ ├── meta-networking
│ └── meta-oe
└── poky
└── meta
Forget about the last variant. We don't want to remove the layer
structure.
Regards,
Andrej
