The Debian Administrator’s Handbook

“We wanted the book to be freely available (that is under the terms of a license compatible with the Debian Free Software Guidelines of course). There was a condition though: a liberation fund had to be completed to ensure we had a decent compensation for the work that the book represents. This fund reached its target of €25K in April 2012.” Raphaël Hertzog and Roland Mas hope that you will enjoy the book.
