The new rewrite of revdep-rebuild is missing the -e/--exact switch, although the manual still specifies it as valid. It would be great to update the manual at least. Implementing the -e would be even better, as I sometimes do use revdep-rebuild together with a big update. Reproducible: Always
Man page update in commit: https://gitweb.gentoo.org/proj/gentoolkit.git/commit/?id=fbe9983453d195bd7995c12ab6cbc6aaa05e6c8b But I'm leaving this bug open, so that we can implement this option in the python version.
