Didn't know it required a kernel to be upgraded. Thought the next reboot if they were removed would to it. Interesting. The script has a reference at end. new-kernel-pkg --install "$KERNEL_VERSION" --kernel-image "$NEW_KERNEL_IMAGE" --initrdfile "$INITRDFILE" --banner "$NAME $VERSION_ID Rescue $MACHINE_ID" First time I ran it, it reported that new-kernel-pkg was missing?? Found that it is in grubby-deprecated, so installed that, and reran it. It then reported that it couldn't find a theme, but it did show up. ran mkgrub-config, so perhaps that had created it?? > So, you could do it just before a new kernel is going to be installed, > and it will happen during install. > Thanks > _______________________________________________ > users mailing list -- users@lists.fedoraproject.org > To unsubscribe send an email to users-le...@lists.fedoraproject.org > Fedora Code of Conduct: > https://docs.fedoraproject.org/en-US/project/code-of-conduct/ > List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines > List Archives: > https://lists.fedoraproject.org/archives/list/users@lists.fedoraproject.org
