Three stages of the UEK8 path fail silently, and the script only handled the last one: 1. Populate. so-repo-sync runs before the highstate deploys the [securityonionkernel] section into repodownload.conf, so the first kernel-aware soup skips the kernel sync. kernelrepo_init_empty then seeds valid-but-empty repodata, leaving an enabled repo with zero packages. dnf resolves it happily and installs nothing, no error. 2. Install. `dnf install kernel-uek` on a UEK7 node sees kernel-uek 5.15 already installed, prints "Nothing to do" and exits 0 -- so the script sailed past the install and died later with a misleading grubby error. 3. Boot. Already handled: grubby only auto-promotes within the running kernel's flavor lineage, so 5.x -> 6.x UEK never promotes on its own. Add ensure_kernel_repo(), which verifies the repo is enabled (necessary because skip_if_unavailable=1 hides a broken repo) and that it can serve a 6.x kernel-uek. When it cannot, a manager runs so-repo-sync to populate /nsm/kernelrepo and re-checks; a minion cannot fix it and exits non-zero pointing the admin at the manager. Airgap managers bail, since their repo comes from the ISO rather than a sync. Install the explicit UEK8 NEVRA instead of the bare package name so the "Nothing to do" exit-0 case cannot mask a no-op, and pin the repoquery to securityonionkernel so a UEK7 kernel-uek in the main repo is never picked. Still idempotent and still never reboots.
