Correct.

Well, normally an SPDX identifier string refers to a specific version
of the license. If the license text is different (even for subtle
reasons), the SPDX identifier string should probably be different.

True, indeed, I had missed that.

I also think it is good enough. But I wanted to point out that the
licensing is in fact a bit more complicated. I personally don't see the
need of having a more detailed LIBBSD_LICENSE description, but I wanted
to point this out so that others can comment on this (Arnout, Yann,
Peter).

Best regards,

Thomas
