Pakete und Kategorien ausschliessen
It is possible to selectively update certain categories/packages and ignore the other categories/packages. This can be achieved by having rsync exclude categories/packages during the step.

Define the name of the file that contains the exclude patterns in the PORTAGE_RSYNC_EXTRA_OPTS variable in :

Beachten Sie, dass dieses Vorgehen zu Abhängigkeits-Problemen führen kann, da neue erlaubte Pakete von neuen aber ausgeschlossenen Paketen abhängig sein können.

Defining a custom repository
It is possible to ask Portage to use ebuilds that are not officially available through the Gentoo repository. Create a new directory (for instance ) in which to store the 3rd-party ebuilds. Use the same directory structure as the official Gentoo repository!

Next, pick a sensible name for the repository. The next example uses "localrepo" as the name:

Tell Portage that the repository master is the main Gentoo repository, and that the repository should not be automatically synchronized (as it is not backed by an rsync server, git mirror or other repository source):

Finally, enable the repository on the local system by creating a repository configuration file inside, informing Portage where the local repository can be found:

Mit mehreren Overlays arbeiten
For the power users who develop on several overlays, test packages before they hit the Gentoo repository or just want to use unofficial ebuilds from various sources, the package brings, a tool to help users keep the overlay repositories up to date.

First install and configure as shown in the Overlays User Guide, and add the desired repositories with.

Aktivieren Sie beispielsweise das hardened-development Overlay:

Regardless of how many repositories are used through, all the repositories can be updated with the following command:

For more information on working with overlays, please read and the previously linked layman/overlay users' guide.

Using Portage with self-maintained software
Sometimes users want to configure, install and maintain software individually without having Portage automate the process, even though Portage can provide the software titles. Known cases are kernel sources and nvidia drivers. It is possible to configure Portage so it knows that a certain package is manually installed on the system (and thus take this information into account when calculating dependencies). This process is called injecting and is supported by Portage through the file.

For instance, to inform Portage about gentoo-sources-2.6.11.6 which has been installed manually, add the following line to :
