Yocto community,
Triggered by the previous email request to yocto@ about best practices
for layer organization I'm finally firing off this email for (hopefully)
some feedback on an idea we first kicked around, discussed for rough
consensus and then decided to implement in the Yocto based GDP project
[1]. You can see it as a trial, anything can be changed, but so far so
good...
We adopted a somewhat novel (but actually not really unique, see inside)
naming convention [2] for all modifications to components that belong to
other layers.
I've been using a similar naming/sorting mechanism in layers that
I maintain for several years now.
Great. Is it similar, or /exactly/ like this? I'm only asking because I
think it would be useful to have some written down rules and if there are
additional tweaks that will improve this proposal, I'd like to hear them.
Exactly. The layer name and recipe-* structure is nested in a layer
that is carrying bbappends. That way there's zero confusion about where
the main recipe can be found.

I suspected it might actually be somewhat of a common practice.
When you have a single layer that is carrying bbappends to many other
layers, I find that it really helps keep everything separated and aids
finding the original recipe.
Yes, that is the idea.
(that being said, recent work with layer index, etc, make it
easier to locate the original recipe and any bbappends .. but that
doesn't preclude keeping things organized in a layer).
... but I didn't get any more feedback than yours, so I'll just leave it
where it is for now. Maybe this is not something the other Yocto community
cares about, or similar practices are actually done in practice, but not
written down. Or maybe everyone is OK with the state of mixing .bb and
.bbappend files within the layers...
So far I think the initial experience on our side is positive. It's
something that needs to be looked after a bit (we have a few mistakes to
fix). But since some directories will only have .bb files, and others only
.bbappend files, it's therefore easy to script a warning system for anything
that is out of place.
Best Regards

Cheers,
