Some man pages (e.g. dnstap-read.1, named-nzd2nzf.1) should only be
installed conditionally (when the relevant features are enabled in a
given BIND 9 build). This is achieved using Automake conditionals.
However, while all source reStructuredText files are included in
tarballs produced by "make dist" (distribution tarballs) as they should
be, the list of pre-generated man pages included in distribution
tarballs incorrectly depends on the ./configure switches used for the
build for which "make dist" is run. Meanwhile, distribution tarballs
should always contain all the files necessary to build any flavor of
BIND 9.
Here is an example scenario which fails to work as intended:
autoreconf -i
./configure --disable-maintainer-mode
make dist
tar --extract --file bind-9.17.11.tar.xz
cd bind-9.17.11
./configure --disable-maintainer-mode --enable-dnstap
make
Fix by always including pre-generated versions of all conditionally
installed man pages in EXTRA_DIST. While this may cause some of them to
appear in EXTRA_DIST more than once (depending on the ./configure
switches used for the build for which "make dist" is run), it seems to
not be a problem for Automake.
