kexec from within initramfs

Question

Can kexec be used from within initramfs to load up a new image and kernel?

It seems that kexec calls shutdown which then looks for /dev/initctl, which is missing from a busybox initramfs image.

Any guidance would be appreciated!

Answer 1

From the kexec man page:

-e (--exec)
      Run the currently loaded kernel. Note that it will  reboot  into
      the loaded kernel without calling shutdown(8).
