For the Debian Project, I recently did some investigation of the claim
that the 4-clause BSD license, which I think is what David is referring
to (since the Regents dropped the advertising clause in 1998, and I
XFree86 was founded years prior), is preferentially used in the XFree86
That license is indeed used, but an MIT-style copyright is used on more
code in XFree86 copyrighted by the Regents than the 4-clause BSD license
is, despite the latter being the representation of the Regents'
copyright license in XFree86's LICENSE file.
The messy truth is that there is code copyrighted by the Regents in
XFree86 under *several* similar but distinct licenses. Some with an
advertising clause, some without. Some GPL-compatible, some not.
My findings follow. Please feel free to ignore the references to
DFSG-freeness, which is a concern primarily for the Debian project, and
my footnote discussion of unpacking a Debian source package.
If this next part bores you, skip to the end for my conclusions.
Again, you do great job in following the licence stuff, and
felicitations to you and to the rest of the X strike force for the soon
to be upcoming 4.3.0-1 package.
I have an interogation about the aim of this mail though. You are
clearly following up on a mail from forum@xxxxxxxxxxx, but in this
response you don't CC them. Is this willed from your part, as a way to
discuss this issue without XFree86 and then inform them about this ? Or
maybe it was only a mistake from your part and you forgot them in your
CC list ? Or maybe some other reason ? Could you please clarify your
position on this point, and eventually forward this list to the
forum@xxxxxxxxxxx mailing list too ?
