I have need to duplicate centos 6 on 133 computers. I purchased a disk duplicator make my master and the duplicator does 11 at a time. All is good so far... When I take a duplicated disk and stick it in the "new" box which is different than the master machine of course all seems to work except the network. So of course the MAC address for the NIC doesn't match so the network doesn't work. My solution was to edit ifcfg-eth0 and remove the HDADDR line and edit udev/70-persistant-net.rules and remove the MAC address from the network SUBSYSTEM line. The network does come back on and everything seems fine. Is this the correct way to do this? Making a master and being able to stick the duplicated disk in another machine? Thanks, Jerry

That way you can install all clients identical with a short command on each client. Some scripting is of course necessary to define the kickstart scripts. Several good tutorials on this topic are available. Below is the a link to the centos intro on this. http://www.centos.org/docs/5/html/Installation_Guide-en-US/ch-kickstart2.html /THomas

With disk duplication I can copy 11 disks in 30 minutes. jerry
