For current RHEL 10 CVM images (for Azure and AWS) we boot the UKI directly instead of having a bootloader in between. Could we have something in the 'Feedback' section about why there's a need to have grub2-cc in between. A few reasons have been discussed in this thread but they're in disparate places :) The proposal seems to target mostly virtual machines: > contains only the modules that are absolutely necessary for VMs, and > natively supports UKI loading So it doesn't *feel* like the bootloader would be there to pave over bad implementations that can't get updated.
