Correct, the glibc manual has a non-trivial invariant section (that is
not the license text itself, that happens from time to time, too).
thanks - that makes sense, especially in light of the article I cited
above, which I don't think I've read before or not recently and sheds
light on the rationale for the invariant section part of GFDL that I
admittedly have always found a bit perplexing.
Reason for asking - I'm trying to finish up the compare of "good"
licenses (for documentation and content) in terms of whether they are on
the SPDX License List, which somewhat recently altered the GFDL
identifiers to differentiate on the invariant aspect due to someone
raising that is makes a difference as to obligations under the license.
So... hence the question of if Fedora considers all versions and
regardless of invariant sections as "good". I think you and Richard have
provided enough for the answer.
I was also inquiring internally as to whether this ever comes up in
questions with Red Hat customers or more broadly and I think that
question may have come across here - sorry about that! I was curious if
the presence of the invariant section being triggered impact comfort
with use of GFDL more widely (beyond Fedora). I hope not...
