Hi,
I have a few identical Dell Optiplex 7010 machines that I want to use for our school's computer room. I tried to clone these installations (like I did before on CentOS 5 and various versions of Slackware), but this time I ran into a problem.
Here's what I did.
Install one computer and zero unused hard disk sectors with dd.
Send the image to a local FTP server using G4L (Ghost4Linux).
Fetch the image on another computer.
Boot the new computer in rescue mode and change the hardcoded
/etc/hostname to a new value.
Let me add that I removed all hardcoded MAC addresses from /etc/sysconfig/ifcfg-em1, which has only very limited information in it.
What else could cause the network to choke on a cloned installation?
Whenever I clone one machine to another (under CentOS 6 anyway) the cloned machine comes up with a different network port, so I have to move /etc/sysconfig/network-scripts/ifcfg-eth0 to ifcfg-eth1 and update all the relevant entries in that file (as well as removing the MAC address).
Cheers, Zube
