推荐使用pungi

这哥们写了不少不错的文章。还有python的设计模式。

pungi --nohash --nosource --nodebugingo -G -C -B -I --name=demo --version=1.0 --destdit=./out -c package.ks
package.ks 是需要安装的包列表。

2. cloud的部署安装

There is a script to create custom iso

1. KICKSTART INSTALLATIONS

2. KICKSTART OPTIONS

3. make the ISO

https://serverfault.com/questions/517908/how-to-create-a-custom-iso-image-in-centos

Create a directory to mount your source.
```
mkdir /tmp/bootiso
```
Loop mount the source ISO you are modifying. (Download from Red Hat / CentOS.)
```
mount -o loop /path/to/some.iso /tmp/bootiso
```
Create a working directory for your customized media.
```
mkdir /tmp/bootisoks
```
Copy the source media to the working directory.
```
cp -r /tmp/bootiso/* /tmp/bootisoks/
```
Unmount the source ISO and remove the directory.
```
umount /tmp/bootiso && rmdir /tmp/bootiso
```
Change permissions on the working directory.
```
chmod -R u+w /tmp/bootisoks
```
Copy your Kickstart script which has been modified for the packages and %post to the working directory.
```
cp /path/to/someks.cfg /tmp/bootisoks/isolinux/ks.cfg
```

Copy any additional RPMs to the directory structure and update the metadata.

cp /path/to/*.rpm /tmp/bootisoks/Packages/.

cd /tmp/bootisoks/Packages && createrepo -dpo .. .

Add kickstart to boot options.

sed -i 's/append\ initrd\=initrd.img/append initrd=initrd.img\ ks\=cdrom:\/ks.cfg/' /tmp/bootisoks/isolinux/isolinux.cfg

Create the new ISO file.

cd /tmp/bootisoks && \

mkisofs -o /tmp/boot.iso -b isolinux.bin -c boot.cat -no-emul-boot -boot-load-size 4 -boot-info-table -V "CentOS 7 x86_64" -R -J -v -T isolinux/. .

(Optional) Use isohybrid if you want to dd the ISO file to a bootable USB key.
```
isohybrid /tmp/boot.iso
```
Add an MD5 checksum (to allow testing of media).
```
implantisomd5 /tmp/boot.iso
```
others

红帽（Red Hat）从Enterprise Server 6.2 开始，启动镜像文件initrd.img 开始改用xz 工具进行压缩，这与以往版本是有区别的

历史关于initrd.img的压缩(制作)及解压的过程

To decompress an image, use the xz -d command. For example

How to unpack and repack an initial ramdisk (initrd/initramfs) image?

三、补充tar.lzma
由于LZMA具有优秀的压缩率及占用资源少的特点，越来越多的工具采用lzma进行打包，后缀名为：tar.lzma。
对于Fedora 11 及以后的版本，可以使用下面的命令操作：
压缩

# tar cfv backup.tar.lzma a/dir --lzma
解压：

# tar xfv backup.tar.lzma --lzma

如果是CentOS 5.3 等老版本，需要安装独立的lzma 工具或用xz 进行：
压缩：

# tar cv a/dir | lzma -c -z > backup.tar.lzma
解压（两个方式都可以）：

# cat backup.tar.lzma | lzma -d | tar xv
# xz -dc backup.tar.lzma | tar xvf -
