That is correct. 

The question is whether this code needs to be Apache 2.0. My understanding
was that the QNX recommendation is that a base port of QNX (aka the
drivers) are recommended to be Apache 2. But it is not clear to me whether
the boot loader needs to be. I don¹t have enough context and can¹t find
any reference to the file system itself in the license guide.

I do not know enough about the subtleties of licenses here and am adding
Brian, in case we need to get some more advice on how to mitigate this
issue.

@Oleksandr, can you also check with your legal guys?
