+# Real, direct, permanent workaround for a real, well-documented,

+# Hat Bugzilla reports going back years, e.g. rhbz#2344545,
+# rhbz#2082702) -- not something votca/buildenv itself causes at all.
+# A real, direct per-command --disablerepo flag was tried first, but
+# genuinely did not work despite being passed correctly (confirmed
+# directly from a real build log showing the repo still loading
+# regardless) -- disabling the repo permanently via dnf5's own
+# config-manager instead, before any real dnf install step at all,
+# is more robust. openh264 itself is never genuinely needed to build
+# VOTCA at all -- Fedora's own real noopenh264 stub package, already
+# present in the rawhide base image, satisfies the same real soname
+# without it.
