As we ship both man pages in one package and drbd 8.4 is (or at least
was at the time) the default, these are the ones you get by default. But
you can also find the 9 ones (man also takes an absolute path).

If you are on Debian, and use our packages (or packages build from our
source), then you can "dpkg-reconfigure drbd-utils" to select the man
page version. Maybe downstream Debian also merged that, have not checked
in a long time.
