The current document ends the last non-code text part of Section 2, Kernel Setup: "It does not matter whether you build the features into the kernel or as a module so long as when the feature is needed, the correct module(s) are loaded (module loading is left to the reader as a fun exercise however)." The final bit in parentheses comes off as a bit elitist, and could be improved. Reproducible: Always Steps to Reproduce: Read http://www.gentoo.org/doc/en/home-router-howto.xml The sentence could easily be rewritten to retain a funny tone, yet be helpful, such as "If your module loading skills are rusty, consult the Gentoo Handbook for examples, particularly Section 3.c on Manual Network configuration."
I don't think that it is elitist, I'd say that it's just an attempt to be funny.
I agree; the sentence isn't offensive imo; rewriting it would just make our translators unhappy.
