Which script takes a file to splat over run-init during ramdisk assembly and calls update-initramfs?

• A. horsepill_setopt
• B. ramdisk_splat
• C. initramfs_patch
• D. horsepill_infect

Answer: (D)

The key idea is that this script is responsible for injecting a payload into the ramdisk by replacing the initial boot handler (run-init) during ramdisk assembly and then making that change permanent by rebuilding the initramfs. The infection script—horsepill_infect—is designed to take a file, splat it over run-init as the ramdisk is assembled, and then call update-initramfs to recreate the initramfs so the patched run-init is used on the next boot. Other scripts may patch or configure parts of the ramdisk, but they don’t complete the combination of overwriting run-init and triggering the initramfs update in one flow.
