It's the value of the SECTION variable. It's supposed to be some kind
of high level classification mechanism for recipes, although I've been
told that is not really that meaningful. We show it for all other
recipes, though, hence showing it for custom images too.

This is pretty much what I got from Paul Eggleton this morning, which
led to the design as is:

All custom images have their license set to MIT. This is because the
license applies only to the recipe (.bb) file, and not to the image
itself. To see which licenses apply to the image you must check the
license manifest generated with each build.

You can see this information if you hover over the little question
mark next to the license value in

Base on the explanation above, it's probably not such a big issue,
since the license of the .bb file is pretty meaningless: what really
matters are the licenses of the image contents, which are reported by
the license manifest. We could inherit the LICENSE of the base image
recipe, although I am not even sure if that would be the right thing
to do.

Paul might have some thoughts on this.

Only the .bb file

I guess you would need to save the .bb file you downloaded into a
custom layer, edit the bblayers.conf file and do bitbake
my-custom-recipe.

You can also import your custom layer into Toaster and build it from
there, although to avoid unexpected behaviour we are going to do some
kind of trick with the layer priorities, probably combined with
enforcing unique names for custom images inside Toaster. Still ironing
out the details of this case.

They go into the meta-custom-images layer for the project within which
you created them.

Each project has its own meta-custom-images layer

Yes. You can see it here

http://www.yoctoproject.org/toaster/project-configuration.html

After some discussion, and since we expose the build system constructs
to users, we concluded it is probably better to be transparent and
show that, like any other recipes, custom images are also provided by
a layer.

No

You can't.

All these details will go into a separate design document that covers
how custom images are created. Will be working on that next week.
