From my work with Fedora, I have a reasonably complete How To Guide that presently runs about 30 pages. Although the process of remastering a distribution is not complex (once it is understood), explaining the how and why of each step does get a bit verbose. For distributions like Fedora that have frequent updates and no decimal releases, having an up to date copy for subsequent installs is a very handy thing. As CentOS normally issues decimal releases, this would not be such a great need. However, having done so many of these remasterings with added content, some other benefits came to light for anyone that does a reinstall or needs to deploy across a number of feature rich machines. In particular, when deploying a feature rich application such as workstations, when anaconda completes the install, there is usually a considerable amount of additional work yet to do. Be this packages from extras, third parties, Gconf settings etc. There is also the task of ensuring all the proper selections were made at installation. Was a check box missed and an item missing or where too many items selected and now using resources and space needlessly? With a customized remastered disk, these issues can all be solved and the deployments made faster and more uniform. The basics of the How To include: Working with comps.xml: Changing the default selections Adding packages to groups Adding new groups Working with the media: Working from a DVD iso or multiple CD iso files. Working with physical media – DVD or CD Collecting files: The various repositories. Using wget to keep your private build repository up to date. Solving dependency hell. Using yum-utils: Using yum-utils to report any missing dependencies makes adding packages much easier. For amusement, last year I built an FC5 distribution that included all files from core, extras and Livna. Yes, it was about 9 Gb when complete, but yum-utils was able to resolve all the dependencies even with a distribution of this size. Adding any RPM file to the remastered distribution: In theory, any RPM should be able to be added to the distribution and automatically installed. In reality, some RPM files do not cooperate well with anaconda and I cover this as well. I also cover what things are more practical to finish with a post install script rather than an RPM or even a custom RPM. I have already modified my script to work with CentOS 4.92 (the iso directory structure was changed by RH or CentOS). As soon as CentOS 5 final is released, I will be remastering my own copy to add in all of my preferred extras to make the desktop sing and dance, utilize my ATI and Nvidea video cards etc. A full function workstation – out of the box. So, if there is some interest in posting this how to on the Wiki, I would be willing to revise the document as needed. To make it CentOS 5 specific or broaden the topic a bit to cover recent releases of RHEL, Fedora and CentOS. Please let me know if this topic is of interest for the Wiki. Mr. Mizzen
