  That's why I say: commit it with (needs review).  That will attract more
reviews than having it either without legal-info, or with the wrong
legal-info.

  The difference is that buildroot users are likely to test the resulting
rootfs, but are very unlikely to look a second time at the output of
legal-info.  It's very difficult to "test" the legal-info - all you have
is "code review". For me, the wrong information in legal-info is an order
of magnitude worse than no legal-info at all.


  That said, none of my dozens of customers ever gave a whit about licenses.
The most they'd do is verify that there's no GPL linked against the app.
So after this post I'll shut up about it.


  Regards,
  Arnout
