ISO Generation

  1. install minimal CentOS6.9
    1.1 network is disabled after firstboot, so enable it
  1. sed -i '/ONBOOT=no/ONBOOT=yes/g' /etc/sysconfig/network-scripts/ifcfg-eth0 
  2. service network restart 

1.2 enable yum cache, so that we can figure out the extra packages under /var/cache/yum/…

  1. sed -i '/keepcache=o/keepcache=1/g' /etc/yum.conf
