Preface
Intended Audience
The FreeBSD newcomer will find that the first section of this book guides the user through the FreeBSD installation process and gently introduces the concepts and conventions that underpin UNIX(R). Working through this section requires little more than the desire to explore, and the ability to take on board new concepts as they are introduced.
Once you have traveled this far, the second, far larger, section of the Handbook is a comprehensive reference to all manner of topics of interest to FreeBSD system administrators. Some of these chapters may recommend that you do some prior reading, and this is noted in the synopsis at the beginning of each chapter.

Changes from the Third Edition
The current online version of the Handbook represents the cumulative effort of many hundreds of contributors over the past 10 years. The following are some of the significant changes since the two volume third edition was published in 2004:
crossref:dtrace[dtrace,DTrace] has been added with information about the powerful DTrace performance analysis tool.
crossref:filesystems[filesystems,Other File Systems] has been added with information about non-native file systems in FreeBSD, such as ZFS from Sun(TM).
crossref:audit[audit,Security Event Auditing] has been added to cover the new auditing capabilities in FreeBSD and explain its use.
crossref:virtualization[virtualization,Virtualization] has been added with information about installing FreeBSD on virtualization software.
crossref:bsdinstall[bsdinstall,Installing FreeBSD] has been added to cover installation of FreeBSD using the new installation utility, bsdinstall.
Changes from the Second Edition (2004)
The third edition was the culmination of over two years of work by the dedicated members of the FreeBSD Documentation Project. The printed edition grew to such a size that it was necessary to publish as two separate volumes. The following are the major changes in this new edition:
crossref:config[config-tuning,Configuration and Tuning] has been expanded with new information about the ACPI power and resource management, the `cron` system utility, and more kernel tuning options.
crossref:security[security,Security] has been expanded with new information about virtual private networks (VPNs), file system access control lists (ACLs), and security advisories.
crossref:mac[mac,Mandatory Access Control] is a new chapter with this edition. It explains what MAC is and how this mechanism can be used to secure a FreeBSD system.
crossref:disks[disks,Storage] has been expanded with new information about USB storage devices, file system snapshots, file system quotas, file and network backed filesystems, and encrypted disk partitions.
A troubleshooting section has been added to crossref:ppp-and-slip[ppp-and-slip,PPP].
crossref:mail[mail,Electronic Mail] has been expanded with new information about using alternative transport agents, SMTP authentication, UUCP, fetchmail, procmail, and other advanced topics.
