c81_mini.xz console version file system. 
c81_gui.xz  GUI release ( password 123456 or 12345678 )
vmlinuz-c81.1 ISO installed kernel
vmlinuz-c81.2 yum upgrade kernel on 2020/06/16
So, each kernel can compatible 2 file system. U can have 4 choices.
  
______________________________________
SOP:
1. Install it to a virtual machine on single sda1 partitioned
1. 只分一个ext4分区的虚拟机用光盘ISO安装
2. disable firewalld / NetworkManager/selinux
2. 使用systemctl 关闭firewalld NetworkManager, vim /etc/selinux/config 關閉selinux
3. config IP with dhclient by modify /root/.bashrc /etc/rc.d/rc.local
3. 为了省事我使用dhclient来分配IP，可以通过修改自动登录使用.bashrc运行dhclient或者先给rc.local授权，然后在 rc.local里面调用dhclient
4. shutdown VM and attach disk to another VM installed Linux
4. 关闭当前虚拟机，把硬盘文件挂在另一台装好了Linux的虚拟机上准备提取文件
5. mount /dev/sda1 /media. My working pack VM use /dev/vda1. so here should be sda1. 
5. 把工作虚拟的硬盘设置为vda，这样sda1就是我们打包的目标，mount 到media
6. mkdir /cpio; cd /cpio; tar -cf rootfs.tar /media/*
7. mkdir fs; cd /cpio/fs; tar -xvf ../rootfs.tar;
8. cd /cpio/fs/media; vim etc/fstab; comment root line, or just rename the file...
9. ln -s lib/systemd/systemd init;
10. rm -rf boot; rm -rf tmp/*;cd var; find . -type f -exec rm {} \;
11. cd /cpio/fs/media;  find . | cpio -oHnewc >../initrd;
12. cd /cpio/fs; xz -z9vf --threads=16 --check=crc32 --lzma2 initrd;
13. cp /media/boot/vmlinuz ... ; cp /cpio/fs/initrd.xz ... ; then u got them;
13. 提取/media/boot里面的vmlinz和 /cpio/fs里面的initrd.xz  你要的东西就打包好了

===================================================================

Note: If u want less memory u must set the tftpboot/pxelinuc.cfg/default with below:
KERNEL vmlinuz-c81.1
APPEND initrd=c81_gui.xz   rootfstype=ramfs
#KERNEL vmlinuz-c81.2
#APPEND initrd=c81_gui.xz   

想少点内存跑起来你还是至少得2xsizeof(initrd)  + 1GB (内核)，注意是cpio而不是xz！内存少自行添加rootfs=ramfs到你的启动选项，可以节省不少内存，但是不推荐这样做，我们要的是力大砖飞！！ 使用KERNEL  vmlinuz-c81.2  initrd=c81_gui.xz rootfstype=ramfs 可以在只有8GB的内存的机器Dell R730启动
