PC-BSD® 9.2 uses pkgng, the next generation package management system for FreeBSD. All of the PC-BSD® utilities that deal with installing or updating non-PBI software now use the pkgng system. This allows users to safely install non-PBI software from the command line without that software being deleted by a system upgrade.

Since FreeBSD does not have an official pkgng repository yet, the PC-BSD® project provides its own repository containing all of the packages that can be built using pkgng.

PC-BSD® provides a custom command, pc-pkg, which is a small wrapper to pkg. When pc-pkg is used with the install or upgrade flags, it will automatically connect to the PC-BSD® pkgng repository using the integrated aria2 downloader utility, which can significantly reduce download speeds over a slow link.

If you are used to using the traditional FreeBSD package system, take note that the commands used to install and manage software differ slightly. For example, instead of using pkg_add to install a package from a remote repository, use pkg install or pc-pkg install (notice there is now a space instead of an underscore).

The FreeBSD Handbook provides an introduction to using pkgng. Section 5.5.1 is not needed on a PC-BSD® or TrueOS® system as the operating system installation does this for you. The various pkgng commands have associated man pages. Type man pkg for an overview of general usage; the names of the associated man pages will be found towards the bottom of this man page. Once you know the name of a command, you can also use the built-in help system to get more information about that command. For example, to learn more about pkg install, type pkg help install.

pc-metapkgmanager

pc-metapkgmanager is the back-end command line utility used by the PC-BSD® installer, Package Manager, and Warden® to manage meta-packages. Meta-packages are like system components, and include supported and unsupported desktops, development utilities, hardware drivers, and miscellaneous applications such as MythTV or XBMC.

PC-BSD® uses pkgsets to determine which system components are available and which applications are installed with each system component. Currently, two pkgsets are available: pcbsd, which defines the available desktop components, and warden, which defines the components available when creating a jail with Warden® or installing a TrueOS® server.

The pc-metapkgmanager command can be used to install or delete meta-packages or to change the default pkgset. If you type the command without any options, it will display its usage:

pc-metapkgmanager
usage: pc-metapkgmanager [options]
Options:
add pkg1,pkg2 <loc>	 -- Add the specified list of meta-packages 
del pkg1,pkg2	  	 -- Delete the specified list of meta-packages
list     	         -- List the available meta-packages
status <pkg>    	 -- List the status of the specified meta-packages
--pkgset <pkgset>	 -- Change default pkgset we are using

To determine which meta-packages are available:

pc-metapkgmanager list | more
Meta Package: Awesome
-------------------------------------
Description: A highly configurable, next generation framework window manager

Required Packages:

Meta Package: Compiz

-------------------------------------
Description: Supported Desktop Environments for your PC-BSD system. 
Icon: /usr/local/share/pcbsd/metaset/pcbsd/Desktops/pkg-icon.png
Desktop: NO
--More--(byte 989)}}

To change the default pkgset, modify the PCBSD_METAPKGSET variable in /usr/local/etc/pcbsd.conf.

To determine if a meta-package is installed, specify its "Meta Package" name as shown in the output of the pc-metapkgmanager list command. For example, to see if the Awesome desktop is installed:

pc-metapkgmanager status Awesome
The meta-pkg Awesome is not installed

To install the meta-package, use the add option and specify the meta-package name. Only the superuser can install meta-packages.

The following example installs the Awesome meta-package. pc-metapkgmanager will provide messages regarding the status of the installation:

pc-metapkgmanager add Awesome 
Pending Meta-Package changes: 1
Installing Meta-Package: Awesome (pcbsd-meta-awesome)

The following 1 packages will be installed:

Extracting ports overlay data...DONE
Finished Meta-Package: Awesome
Meta-Package changes finished!

To delete an installed meta-package, specify its name. Only the superuser can uninstall meta-packages. As seen in the following example, pc-metapkgmanager automatically determines which dependent packages are still needed by other applications and which can be safely removed.

pc-metapkgmanager del Awesome
Pending Meta-Package changes: 1
Removing Meta-Package: Awesome
Removing: pcbsd-meta-awesome
The meta-pkg Awesome is not installed
