* 不会有LINUX 下众多的内核升级版本，长期、稳定的内核版本，方便软件和硬件厂商的支持（当然想要
发展成熟，还需要若干年 时间）；
* 方便的 PBI 软件包格式（减少了LINUX 下常见的库依赖问题，类似于 WINDOWS 下的 EXE 可执行文件
安装方式）；
* 版本号与 FREE-BSD 同步
有趣的版本号命名规则：

AboutPC-BSD ProjectPackage Management
PACKAGE MANAGEMENT
Part of making a Desktop Operating System that people feel immediately comfortable with is ensuring that software installation is as easy and familiar as possible. PC-BSD has taken this approach when developing the PBI (PC-BSD Installer or Push-Button Installer) file format. Programs under PC-BSD are completely self-contained and self-installing, in a graphical format. A PBI file also ships with all the files and libraries necessary for the installed program to function, eliminating much of the hardship of dealing with broken dependencies and system incompatibilities. PBI files also provide developers and packagers with advanced scripting and user interaction in an entirely graphical format, making the entire install procedure similar to what a user would expect from other popular graphical operating systems.
Features of the PBI System include:
Completely graphical extraction & installation process.
Advanced scripting support - Use shell-scripts to control the installation process.
Corruption detection - Ensures that a user's downloaded PBI is intact.
Library auto population - Grabs all the library files a binary may need for operation during the creation process.
Icon Management - Allows developers to set icons for both the desktop & K-Menu.
Program Error Detection - If a PBI installed binary fails and silently outputs a stderr / stdout message, this is captured and displayed in a GUI for troubleshooting.
Easy Removal - PBI's can be removed through the "Remove Programs" system utility.
PBIs can be found at PBIdir.com or in the AppCafe® utility in PC-BSD.
