Again, the DHCP request that gets a response "use this file" comes from the firmware, not the OS. It goes something like: - BIOS/UEFI configured for network boot sends DHCP request - DHCP server says "use this file (aka shim)" - BIOS/UEFI loads that file and runs it - shim loads grub2 or pxelinux, they get their configs/menus - you choose an OS to load - grub2/pxelinux fetches kernel and checks the signature and fails it it doesn't match The step that has to change between Fedora and RHEL is step #2, when the DHCP says "use this file", and at that point, the only thing involved is the BIOS/UEFI firmware. The only available info at that point is some very minimal hardware info like the MAC address. After that, it's too late to change. -- Chris Adams <li...@cmadams.net> _______________________________________________ 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, report it: https://pagure.io/fedora-infrastructure/new_issue
