If I do a first installation I write a script documenting everything I change after deploying a base system (e.g. changes in /etc, installing of packages, creation of directories or symlinks etc.) Later I do a network boot, installing the base system, running the script and restore data. Advantages: The script documents my machine and I always know what a machine does. A new installation is always clean and does not contain traces of former try and error procedures, reconfigurations etc. I can use it with newer OS and software versions. (OK, I have to check it once). It is easy to convert a machine from running service A (e.g. FTP) to a machine serving B (e.g. a mail server). If I am in need of faster recovery I have a bunch of harddisks or even blades ready to go. Imaging is a tool created by whimps to copy Windows systems (where installation does black magic and usually needs interaction;-). And imaging is a source of wealth for manufacturers. See the license fee for the IBM Director Remote Deployment Module. As A UNIX admin familiar with a routine described above I do not see many advantages. Regards Peter
