Which patch enables run-init support in klibc for modern Ubuntu systems?

• A. klibc-horsepill.patch
• B. klibc-runinit.patch
• C. klibc-init.patch
• D. runinit-klibc.patch

Answer: (A)

Run-init is the small program inside the initramfs that hands off boot control to the real system init. To support this flow in klibc-based initramfs on modern Ubuntu systems, a patch must add the run-init entry point and the minimal startup glue that launches the real init with the correct arguments and environment. The klibc-horsepill.patch is the patch associated with adding run-init support in this context. Its changes are specifically aimed at enabling the run-init pathway so Ubuntu’s boot process can proceed smoothly from the initramfs into the real init. The other patch names imply different changes or are simply alternative labels that don’t match the patch used to enable this capability in current Ubuntu releases, so they’re not the appropriate choice.
