LPI Linux Certification in A Nutshell 3rd edition, Adam Haeder, O’Reilly, 2010
This certification may be useful to Linux system admins. Too bad they have left out virtualization, which most job reqs will include. It will appear in a ‘level 3 specialty’. In any case, the book is a good summary of Linux admin tasks. 450 pages.
