This is an ongoing issue. For the first part of system, a few year ago, I installed Centos 5.6 to some server via USB-DVDROM. there was no problem. For now, I have to install again and the number of servers is not less
And in the future, I will do it again, again.
Centos 5.6 should be same for all system. All the server, old and new, should be replacable.
In the link you send, there is nothing about "install.img". However when I started kickstart, this file is always asked.
Is there a way to cerate/build such an image from an OS directly?
