Well, I don't really care whether we call it IGNORE or NOTHING or
whatever makes more sense. I'm also fine with deprecating YES and NO
to replace them with more meaningful values.
What I care about is having the ability to mark a package for the
following conditions:
- redistribute "source" archive, list in the manifest and save
licensing files,
- list in the manifest and save licensing files,
- completely omit the package from legal-info.
As Luca explained, there are packages for which we should not
redistribute the "source" archive, but which we must list in the
manifest. Luca talked about imx-vpu, I was thinking about
nvidia-driver.
The new possibility that I would want is to completely ignore the
package from the legal-info output, as there might be legal reasons that
the mere existence of that package should not be disclosed.

Yann E. MORIN.
