红帽全球峰会21.3. UEFI Secure Boot support
You can install and run Red Hat Enterprise Linux 10 on systems with enabled UEFI Secure Boot if the kernel and all the loaded drivers are signed with a trusted key. Red Hat provides kernels and drivers that are signed and authenticated by the applicable Red Hat keys.
If you want to load externally built kernels or drivers, you must sign them as well.
- Restrictions imposed by UEFI Secure Boot
- The system only runs the kernel-mode code after its signature has been properly authenticated.
- GRUB module loading is disabled because there is no infrastructure for signing and verification of GRUB modules. Allowing module loading would run untrusted code within the security perimeter defined by Secure Boot.
- Red Hat provides a signed GRUB binary that has all supported modules on Red Hat Enterprise Linux.
