In 2001⁄2002 I wrote for LinuxFormat a two parts tutorial for end users on how to configure Gnu/Linux desktops on limited hardware, that in part summarized what we were then doing in the RULE project. Before the actual tutorials, I had also written down my own, very personal motivations for playing with that kind of tricks. The reason was to clarify, first to myself and then to the editor, what itches I would try to scratch, so that text was never published, and I basically forgot about it.
