This allows an administrator to update the components independently without requiring rebuilding xen, as well as to replace the components in an existing image. The resulting EFI executable can be invoked directly from the UEFI Boot Manager, removing the need to use a separate loader like grub as well as removing dependencies on local filesystem access. And since it is a single file, it can be signed and validated by UEFI Secure Boot without requring the shim protocol. It is inspired by systemd-boot's unified kernel technique and borrows the function to locate PE sections from systemd's LGPL'ed code. During EFI boot, Xen looks at its own loaded image to locate the PE sections for the Xen configuration (`.config`), dom0 kernel (`.kernel`), dom0 initrd (`.initrd`), and XSM config (`.xsm`), which are included after building xen.efi using objcopy to add named sections for each input file.
