BIOS: no because that distro installer will overwrite the Fedora GRUB, and the distro installer will not support BLS drop-in scripts because the format and parsing code are not upstream; so while it will create a menu entry for the Fedora instance, it will not work. UEFI: yes. grub-mkconfig + os-prober should discover the Fedora GRUB instances, and create a chainloader boot entry to execute the Fedora specific GRUB EFI OSLoader. Further, since current BLS format doesn't allow pointing to other devices or partitions, and paths are assumed to only be relative to $BOOT, any bootloader not on $BOOT must be referenced in the bootloader's native configuration format rather than by BLS drop in snippet. -- Chris Murphy _______________________________________________ devel mailing list -- devel@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to devel-leave@xxxxxxxxxxxxxxxxxxxxxxx Fedora Code of Conduct: https://getfedora.org/code-of-conduct.html List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/devel@xxxxxxxxxxxxxxxxxxxxxxx/message/NO3WAMOROIIX3AQM5ISLIX47VNLDROCA/
