are a commercial vendor.
I'm not entirely sure what you mean by "bring in" in this context or
what the underlying rationale for your reluctance is. But some general
comments:
Support and testing.. if the recipe is there we have to support it, if
we don't ship it to our customers -- they are free to source it
themselves, but it's clear that we didn't test and don't support it.
We provide it, customers expect us to support it. We're not willing to
support meta-oe due to the number of recipes in it. oe-core,
meta-yocto, meta-networking, meta-selinux, meta-webserver, and others we
do use, test and provide to our customer.
Does this mean we should look at splitting meta-oe into more layers? Or
is this issue unique to Wind River?
I think there is merit in looking at the contents of meta-oe over time and
splitting them up into functional units. However, at this point I don't have
any direct suggestions as to what those units would be.
At some point, the layer dependencies get out of hand.
Yes they do. The number of layers and contents of them also have to be
reevaluated over time. What makes sense for one release may drastically change
in the future and we have to be willing to adapt to the changing configurations.
I think for the most part the sublayers within meta-openembedded are at
roughly the right level. It's the general "meta-oe" that is the issue for us.
(Too many things we're not willing to support.)

It's entirely possible to have a copy of meta-oe on hand and only
include a subset of the recipes in the parse. You can do that either by
adding the layer and then BBMASKing out everything you don't want, or by
not adding the layer as such but just admit individual recipes by adding
them to BBFILES specifically. Either of those approaches would avoid
the risk of accidentally introducing dependencies on recipes from
meta-oe without realising that this is what you are doing.
Also, I think the toxicity of meta-oe nowadays is much less than it used
to be (thanks mostly to excellent work by Paul in cleaning up
I agree, it's significantly better now. I do use meta-oe from time to
time on personal projects...
the .bbappends and overlapping recipes) and, as far as I know, the act
of including meta-oe in your layer list no longer leads to the sort of
random changes to recipe versions and behaviour that you might have
gotten burned by in the past. So if your previous experience is from
some time ago then you might want to give it another try.
