A collaborative, short-term open source authoring project to quickly write a book covering the basics from the 2005 BSDA Certification Requirements Document was recently started. The BSD Certification Group's BSDA (BSD Associate) Certification is for BSD Unix system administrators with light to moderate skills.
Using a wiki, authors, reviewers and readers all contribute to complete the book by the end of February. This bsdwiki contains over a hundred pages each with the topics defined by the BSD Certification Group. And a PDF in book format is periodically generated from this wiki content.
