- update to 2.10.2: * Regenerating man-db's build system now explicitly requires Automake >= 1.14. (This was already the case since at least man-db 2.10.0, but was previously undocumented.) * Make `man -H` sleep for a few seconds after starting the browser, since it may background itself before loading files (Dr. Werner Fink). * If an override directory is configured using `--with-override-dir`, it is now applied more consistently when building the manpath, and whether a page was found in an override directory is considered when sorting candidates for display (Mihail Konev). * Make the man-db manual build reproducible. * Add some hardening options to the `systemd` service. * `configure` now has a `--with-snapdir` option, for use on systems where `snapd` is configured to use a directory other than `/snap`. * Fix occasional `mandb-symlink-target-timestamp` test failure. * Fix inadvertent reliance on a GCC extension that caused build failures with Clang. * Fix building without `iconv`. - drop man-db-2.7.1-firefox.dif (upstream) OBS-URL: https://build.opensuse.org/request/show/998716 OBS-URL: https://build.opensuse.org/package/show/Base:System/man?expand=0&rev=142
