From: Herton R. Krzesinski <[email protected]> redhat: drop certificates that were deprecated after GRUB's BootHole flaw
Bugzilla: https://bugzilla.redhat.com/show_bug.cgi?id=1994849 Since newer RHEL should already have newer enough grub versions, we don't need anymore to keep signing the kernel for secure boot with older keys for compatibility with older grub. The second signature also causes problems because the upstream kernel so far does not support checking more than one signature as reported on bug above, where kexec signature checking can fail in a secure boot enabled environment. More than one signature requires that we patch the kernel for it to work, but we don't need that now since we can drop the second signature. Signed-off-by: Herton R.
