When the kernel binary happens to be too big things break because the end of the kernel will overlap with the start of the initrd due to the fixed offsets used and thus the fixes space being available for the kernel binary (and the other things being added to the uki, except initrd which comes last). Which is not the case right now with fedora kernels, so everything works fine. take care, Gerd _______________________________________________ devel mailing list -- devel@lists.fedoraproject.org To unsubscribe send an email to devel-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/devel@lists.fedoraproject.org Do not reply to spam, report it: https://pagure.io/fedora-infrastructure/new_issue
