Our client wants us to clone the OS from one machine onto all the others such that all systems are “identical” from an OS perspective. Can someone give me a general outline of steps to take that will result in multiple identical machines while avoiding some of the “gotchas” like overwriting the /etc/fstab file. Etc? Obviously, I found that one first hand. In advance, thank you.<BR>Jerry</SPAN></FONT> </FONT></BODY></HTML>
