Except in the last handful of releases, /boot/efi/EFI/fedora/grub.cfg won’t have any boot options. Today it just is a simple file to load /boot/grub2/grub.cfg. And THAT file doesn’t have any specific kernel entries, it just loads blscfg, and the kernel entries are each defined in a file in /boot/loader/entries/. There is the default kernel command line defined in the grub.cfg that on a vanilla install, is referenced in each bootloader spec file in /boot/loader/entries/ but as soon as you use grubby to change it, the kernel parameters get hard-coded into each file, so it’s possible to have a different set of kernel options in each file, as well as in the grub.cfg. Also, if someone has replaced the grub.cfg in EFI with one created by grub2-mkconfig, there’s now yet another place to get lost adding options. Then there is the confusion of the /etc/grub2.cfg and /etc/grub2-efi.cfg symlinks. I’ve seen advice that say to use `sed -i.old ‘s/rhgb quiet//‘ /etc/grub2.cfg` which replaces the symlink with a real file, making all sorts of things break. This is why Fedora always suggests using grubby. -- Jonathan Billings _______________________________________________ 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 Do not reply to spam on the list, report it: https://pagure.io/fedora-infrastructure
