As a UEFI PE format kernel image becomes more popular, there is a need for kexec to reboot those kinds of images. After the introduction of the UKI (another PE), at present, there are three competitive methods to support that goal, but all of them have pros and cons.[1] It seems that none of them can be accepted in the near future. Therefore, we are resorting to the user space kexec-tools to parse the UKI format for the time being. By parsing the UKI, systemd-stub is stepped around and PCM will not affect the boot up of the second system.
