mkisofs -o MYOS.iso -b isolinux.bin -c boot.cat -no-emul-boot -boot-load-size 4 -boot-info-table -R -J -v -T isolinux/
二
1 安装一个简洁的系统
2 安装 anaconda,anaconda-runtime
3 mount,mkdir /centos,cp光盘内所有到/centos
4 剪裁软件包,可根据install.log,放到 /centos/centos,也可直接替换CentOS
5 cd /centos,createrepo -g repodata/coms.xml . 执行两次
6 cp anaconda-ks.cfg ks.cfg
vi isolinux.cfg
default linux > default linux ks=cdrom:/ks.cfg
7 make iso
mkisofs -o MYOS.iso -b isolinux/isolinux.bin -c isolinux/boot.cat -no-emul-boot -boot-load-size 4 -boot-info-table -R -J -v -T centos/
