Building and Customizing Rock Linux
"First off, this section does not cover the creation of distributions, but building and customising existing ones. [...]
Before you start building a distribution - just as before you start anything else in life - you must know what you want to do. There are many things you can do in ROCK, some are obvious, some are not. Here's an (incomplete) list of things you can do:
* optimise for a given processor
* cross compile for another architecture
* create live systems for working from a ROM-device
* create highly specialised systems that do one thing and one thing only
* select default programs for given task:
o cups vs. lprng
o sendmail vs. exim vs postfix
o colored init vs. plain init
o ...
Many of these things you don't have to do, but you can and you should keep that in mind during the next steps."
