i believe that the ramdisk is one of the files that gets checked when the phone boots up on the 4.3 bootloader. Im not a dev, i just know alot, so feel free to correct me on this.
Phone: Galaxy S3

Ramdisk in another word "initramfs", abbreviated from "initial*ram file system", is the successor of*initrd. It is a*cpioarchive of the initial*file system*that gets loaded into memory during the*Linux startup process. The*Linux kernel*mounts it as*root file system*and starts the*initprocess from it. This will complete certain tasks before the real root file system is loaded; thus, initramfs needs to contain all of the*device driversand tools needed to mount the real root filesystem.

Source wikipedia.

Every rom has its own initramfs so can loaded at device start.
As I had compiled kernels for galaxy s variant, I had used same kernel with different ramdisks to boot cm10, 10.1 , 10.2 and 11.
Check my signature.

Will uploud a patched safestrap apk so some body with unlocked bootloader can test if can dual boot 4.1 and 4.3 and maybe kitkat soon.

There are already a couple dual boot recoveries out for the unlocked people. Just make sure if you do modify and upload safestrap you get permission from the creator. Its kind of rude to modify and hand out other peoples work even if you give credit where credit is do unless you ask first.
ADB Only (Windows)
ADB Only (Linux) <-- Plus instructions

I know there is a couple of dual boot recoveries for unlocked people.
In first order my goal is to make it work for people with locked bootloader like me.
Second, I wont upload safestrap without get permission from @Hashcode and make sure it fully safe and stable.
