Ah, two problems are there. First, I forgot
dnsperf on f32 still depends on bind-libs. Second, I haven't waited long enough before building
bind-dyndb-ldap. Even when built on side-tag directly, I should have waited for wait-repo first. My build of bind-dyndb-ldap were started after bind were done, but not yet propagated to repo. So new builds of both are required.
I think it will make it fail again. gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-fedora-$releasever-$basearch for releasever=35 does not provide any arch link to gpg key. As soon as packages would be signed by new GPG key, it would fail to verify on such installation. Upgrade to more recent version, including rawhide, would require disabling gpg verification.
Issue with generated manual pages were found in this build. Some manual pages were correct (named, dig), while others were left broken from upstream (named-checkconf). Modified build not only rebuilds all manual pages, but also html and pdf documentation in doc package.
