Fedora 45 Considering A Lightened GRUB Bootloader For Confidential Compute
Fedora 45 is considering a lightened version of the GRUB UEFI bootloader for confidential computing. This minimal implementation would focus on UEFI boot, UEFI Secure Boot, and handling Unified Kernel Images and Bootloader Specification files. The standard GRUB bootloader would remain available as the default in Fedora Linux, while the lighter version would be used for confidential compute VMs.
- ▪Red Hat engineers are proposing a separate, minimal package of the GRUB bootloader for confidential computing.
- ▪The lightened GRUB bootloader would be focused on UEFI boot and handling Unified Kernel Images and Bootloader Specification files.
- ▪The goal of the lighter GRUB version is to maintain the same TPM PCR values longer for a more stable confidential computing experience.

Fedora 45 Considering A Lightened GRUB Bootloader For Confidential Compute Written by Michael Larabel in Fedora on 13 June 2026 at 08:22 AM EDT. Add A Comment Among the changes being considered for the in-development Fedora 45 is a lightened version of the GRUB UEFI bootloader that would focus on being a minimal implementation suitable for confidential computing. Red Hat engineers are considering a separate, minimal package of the GRUB bootloader that would be focused just on UEFI boot, UEFI Secure Boot enabled, and the bare minimal number of built-in modules while also being able to handle Unified Kernel Images (UKIs) and the Bootloader Specification (BLS) files.
