This article is a work-in-progress referring to a future Portage version. It does not apply to the current Funtoo Portage version. Please do not update your configuration yet.
Starting with Portage-2.3.8, a switch to a new repository configuration framework is complete and users may want to update their configuration files. This document aims to describe the goals for the new framework and how to use it.
Multiple repository layout
One of the most important changes is the switch from the old overlay layout to a new cleaner repository system. The new layout is more flexible and more predictable. For example, repositories can now use resources (eclasses, for example) provided by other repositories.
The old layout was based on the concept of one main tree and optionally a number of overlays. The main tree provided base system ebuilds, eclasses, profiles, while overlays mostly were able to provide their own ebuilds. The ebuild provided by overlays overrode the ebuilds in main tree to the extend of making it impossible to install the main tree version. Overlays could also provide eclasses for their own ebuilds and package.* entries that applied to all overlays and to the main tree. The Package Manager is responsible for updating the main tree, while overlays are managed externally.
The new layout is based on the concept of one or more configurable repositories. Each repository can either be stand-alone or depend upon other repositories. The distribution provides a repository called funtoo (a drop-in replacement for Gentoo's gentoo repository). Users can install more repositories at they will, the repositories providing their own ebuilds, eclasses and profiles as necessary and/or using them from other repositories. Users can explicitly choose the repository they want to install packages from. The Package Manager can update all repositories.
Portage configuration
New repository layout
The repository configuration should be stored in /etc/portage/repos.conf. It can be either a single file or a directory containing one or more .conf files.
The default configuration is installed as /usr/share/portage/config/repos.conf. This file is internal configuration file installed with portage ebuild and should not be modified. Instead, the configuration in /etc/portage/repos.conf can override the defaults specified there.
The configuration uses format similar to Windows .ini files. Each section heading (repository name in square brackets) signifies a single repository, followed by one or more key-value option pairs. For example, the following file copies default configuration for Funtoo repository:
/etc/portage/repos.conf/funtoo.conf - Example configuration override for Funtoo repository[funtoo]
# moved to non-default location!
location = /var/db/repos/funtoo
sync-type = git
sync-uri = git://github.com/funtoo/ports-2015.git
auto-sync = yes
Location variable is what used to be a PORTDIR, when using old-fashioned /etc/portage/make.conf. /var/db/repos/funtoo is a dummy location example. Default location in Funtoo is set to /usr/portage. Users are free to choose a location of their suits. sync-type is a CVS type used for portage tree, git is a default in Funtoo. sync-uri is what used to be a SYNC variable, when using old-fashioned configuration through /etc/portage/make.conf
The most useful repository configuration options are listed below:
- location
- Obligatory. Specifies the directory where repository is/will be stored. If Portage knows how to sync the repository and the location does not exist, it will be created on next emerge --sync. Otherwise, the directory must exist.
- priority
- Specifies the priority used for ordering ebuilds from different repositories. If two repositories provide an ebuild with matching versions, the repository with higher priority will be used.
- auto-sync
- Specifies whether emerge --sync should update the repository. Defaults to yes if sync-type is specified, no otherwise.
- sync-depth
- Specifies --depth for git clone. Used only on initial sync. Defaults to 1. Can be set to 0 to force full clone (not pass --depth at all).
- sync-type
- Specifies syncing/update method. Can be one of: cvs, git, rsync, svn.
- sync-umask
- Specifies the umask used when updating/syncing the repository.
- sync-uri
- Specifies remote URI from which the repository will be cloned/synced. Can use any syntax valid for a particular syncing method.
- sync-user
- Specifies the user[:group] used to update/sync the repository. If FEATURES=usersync is used, defaults to the credentials of directory owner.
