The conclusion was that the docs are licensed under the same license as
the source code (simply: do whatever you want, but preserve the
BSD-style copyright notice available with the source code).

afaict, that actually did not happen for Bruce's book (no copyright
notices other than Addison Wesley). But presumably A-W will not try to
push their apparent copyright on our docs ;)

istm that a paragraph at the front with the copyright notices about
"Portions of this book are from... which is copyright..." might be
appropriate in most cases.

This contribution is a standalone "article" in the DocBook sense, so
does not depend on other docs or pieces of docs. But it *does* raise
some encumbrances wrt keeping the source code available for a year after
the last formatted version is distributed. Not sure how we guarantee
that, since we don't have an official mechanism defined to preserve
tarballs etc for posterity :(

afaict, the FDL does not specifically allow one to replace a version
with a newer version, and asks that the original sources be kept intact,
at least to meet the 1 year source code rule.

otoh, someone probably has old tarballs saved (I used to, until my MO
drive failed).
