Understood. I was thinking that the db was generated every time you
updated or installed packages. That's how Debian and its derivatives
do keep it up-to-date. (Actually, they only run mandb if 1 or more of
the updated/installed packages have manpage. It's handled by their
"dpkg trigger" feature.)

Thanks, I have a much better understanding of the situation now. I
agree that there is no simple solution.
