Overview

emgrip-dupes scans the Grip repository Packages data and configuration, identifies the supported list of components in the requested suite.

In some cases, these duplicates are useful and only a small amount of space is taken up by the extra listing. However, the version in one component can easily be out of sync with the version in another.

The main emphasis is on the size of the Packages file for the 'main' component (the one that every user needs to download). Purge mode will remove the listing of the specified package from 'main'. Merge mode will bring the outdated version into line with the most recent version of the package so that all components list the most recent version.

Limitations

Next step is to automate the "correction" of the duplicates but this does need care. Manual corrections involve identifying the packages to retain in main (where the duplicate in dev, doc or debug is not wanted) and pass those to --trim.

The more complex case is to remove from main (e.g. package name suffix is -dev or -doc or -dbg or the Section is devel, dbg, doc or libdevel). emgrip-dupes --purge removes each binary separately because removing the package from main in a single operation will also remove the source. This is a particular problem if the source package also builds binary packages that are intended for main, e.g. dbus.
