6.1.5. Trial-and-Error Method

Until recently, the only way to populate the contents of your root file system was to use the trial-and-error method. Perhaps the process can be automated by creating a set of scripts for this purpose, but the knowledge of which files are required for a given functionality still had to come from the developer. Tools such as Red Hat Package Manager (rpm) can be used to install packages on your root file system. rpm has reasonable dependency resolution within given packages, but it is complex and involves a steep learning curve. Furthermore, using rpm does not lend itself easily to building small root file systems because it has limited capability to strip unnecessary files from the installation, such as documentation and unused utilities in a given package.
