pc-metapkgmanager is the back-end command line utility used by the PC-BSD® installer, System Manager, Update 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.

Beginning with version 9.1, PC-BSD® uses metapkgsets to determine which system components are available and which applications are installed with each system component. Currently, two metapkgsets 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 PC-BSD® server. You can view the contents of these metapkgsets on trac[1].

The pc-metapkgmanager command can be used at the command line to install or delete meta-packages, update to the latest package set, or to change the default metapkgset. 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 
                           <loc> should be a FTP / HTTP url where pkg_add 
                           can fetch packages, or an absolute path to 
                           location of pkg files on disk.
 checkup		 -- Check for updates to pkgs
 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
 update pkg,pkg2 <loc>  -- Update system packages. Can use 'all' or <pkg,pkg2>.
                           <loc> should be a FTP / HTTP url where pkg_add 
                           can fetch packages, or an absolute path to 
                           location of pkg files on disk.
 --pkgset <pkgset>	 -- Change default pkgset we are using
 --chroot <dir>	 -- Operate on the directory specified using chroot

Finding, Installing, and Uninstalling Meta-Packages

To determine which meta-packages are available:

pc-metapkgmanager list |more
Meta Package: Awesome
-------------------------------------
Description: A highly configurable, next generation framework window manager
Icon: /var/db/pc-metapkgmanager/pkgsets/pcbsd/Awesome/pkg-icon.png
Parent: Unsupported-Desktops
Desktop: YES
Required Packages:

-------------------------------------
Description: Development tools and utilities for your Desktop
Icon: /var/db/pc-metapkgmanager/pkgsets/pcbsd/Development/pkg-icon.png
Desktop: NO
--More--(byte 989)

To view which meta-packages are available in an alternate metapkgset, specify the metapkgset name. For example, to view the available warden meta-packages from your desktop, use this command:

pc-metapkgmanager --pkgset warden list | more
Meta Package: Apache

Icon: /var/db/pc-metapkgmanager/pkgsets/warden/Apache/pkg-icon.png

a high-quality learning experience to remote students.

Required Packages:

Category Entry 
Meta Package: Development
-------------------------------------
Description: Developement tools and utilities

--More--(byte 989)

To permanently change the default metapkgset between pcbsd and warden, 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. If you do not specify the URL, the default mirror will be used. If you receive an error when downloading the package, you can change the default mirror in Control Panel ➜ System Manager ➜ Mirrors.

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

pc-metapkgmanager add Awesome

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

<snip output of other required packages>

Upgrading Meta-Packages

pc-metapkgmanager can also be used to determine if any meta-packages are out of date and to update meta-packages. To determine if any meta-packages have newer versions:

pc-metapkgmanager checkup
All packages are up to date!

In this example, all meta-packages are at their latest versions. If any were out of date, you would instead receive the message "The following package updates are available:" followed by the names of the out-of-date meta-packages.

To update a meta-package, use the pc-metapkgmanager update command followed by the name of the specific meta-package or the word all to update all out-of-date meta-packages.

pc-metapkgmanager records any error messages to /tmp/.pc-metamanager.log. This log file automatically rotates whenever it reaches 5MB in size.
