Some initrd that using systemd, isn't serverd as a general purpose boot initrd. In case of kdump, 2nd kernel initrd is used to mount non-root local/remote filesystem and dump vmcore there. The kdump script is running right before switch-root and will reboot after saving vmcore. So mounting sysroot isn't quite justified in this case. But it's still acceptable (since it's readonly mount), as long as it's not keeping systemd from reaching initrd.target (so kdump script can run later).
