[CentOS-devel] how to use livecd-creator to create my own livecd iso which is same as offical release iso？

 Hello list,
    I use the livecd-creator to customize my own livecd iso. I use the
kickstart config file from https://raw.githubusercontent.com/CentOS/
sig-core-livemedia/master/kickstarts/centos-7-livecd.cfg.
    #livecd-creator -v --config centos-7-livecd.cfg --cache
/var/cache/livecd
    finally I got a iso, but the iso is strange.
    The offical distribution iso is
    CentOS-7-x86_64-Minimal-1511.iso
    |+++EFI
    |+++images
    |+++isolinux
    |+++LiveOS
    |+++Packages
    |+++repodata
    |+++.discinfo
    |+++.treeinfo
    ......
    |+++RPM-GPG-KEY-CentOS-Testing-7

    But the iso created by livecd-creator is show as following:
        My-own-test.iso
        |+++EFI
                |+++BOOT
                        |+++fonts
                        |+++BOOTX64.EFI
                        |+++grub.cfg
                        |+++grubx64.cfg
        |+++isolinux
                |+++boot.cat
                |+++initrd0.img
                |+++vmlinuz0
                ....
        |+++LiveOS
                |+++osmin.img
                |+++squashfs.img

My questions is how to use livecd-creator to create my own livecd iso as
same as offical release iso
