The size and complexity of the LPI tests required the collaboration of numerous authors and reviewers to get this edition done. Material was contributed by Bj⊘rn Ruberg (Sendmail, DNS, networking, printing), Adam Haeder (file and service sharing, web services), and Faber Fedor (troubleshooting).
For the second edition, we thank reviewers Keith Burgess, Donald L. Corbet, Chander Kant, and Rick Rezinas.
Bruno dedicates his work to his grandfather, Oswaldo Cabral Pessanha, in memorium.
