This document explains how to install software straight from our overlays.
Configuration and usage of the overlays
What is an overlay?
An overlay is simply the place where people put third party ebuilds. These ebuilds undergo extensive testing before they can be put into the Portage tree. Currently there are two overlays available: vdr-testing and vdr-1.5. If you want software around the VDR which is tested to become finally part of the main tree you can use the vdr-testing overlay. If you want the most recent development versions of the VDR you have to use the vdr-1.5 overlay. In the following we use the vdr-testing overlay as example.
Installing and configuring layman
# emerge -av layman
Even though we've installed app-portage/layman, we can't install packages just yet. First you will need to tell Portage you want to use a local repository. This can be done with these simple commands:
(First we create a needed file. It is alright if it already exists.) # touch /usr/portage/local/layman/make.conf # echo "source /usr/portage/local/layman/make.conf" >> /etc/make.conf
Next, we'll have app-portage/layman check out (
git clone ) the repository for /usr/portage/local/layman/vdr-testing/ :
# layman -a vdr-testing ... * Successfully added overlay "vdr-testing".
Installing sources from our overlays
Now you can start using the ebuilds from the VDR overlay. Point your browser to http://overlays.gentoo.org/proj/vdr/browser/testing and choose a few packages.
These packages will be masked by an ~arch keyword. Before you can
emerge them, you will need to add them to your /etc/portage/package.keywords . Here are a couple of examples:
# echo "media-tv/vdrseriestimer" >> /etc/portage/package.keywords # echo "media-plugins/vdr-burn" >> /etc/portage/package.keywords
Now you can install them with a simple
# emerge -av vdrseriestimer vdr-burn
Packages in the VDR overlays are under rapid development. Packages listed in this guide may not always be available: they may have been moved to the official Portage tree, or they may have been removed from the overlays for technical reasons.
Don't forget to keep your VDR overlays up to date:
