Initial Implementation of Package Sets

OSCAR provides a basic notion of package sets, however the capability has never been fully implemented. This document presents the current status for an initial implementation of package sets, which will be enhanced/extended by the more complete implementation being pursued by Wesley Bland (Package Set Manager).

The current notion of a Default Package Set has been implemented, which is used to exclude OPKGs on a given Linux distribution.

Package Set Architecture

All package sets are defined in $(OSCAR_HOME)/share/package_sets/. In that directory a file describes a given package set for a specific Linux distribution and hardware architecture. They are organized as follow: ‘’$(OSCAR_HOME)/share/package_sets//--.xml

This allows us to maintain different files for each Linux distribution.

The schema of the XML file describing a package set is shown here:

<?xml version="1.0" encoding="ISO-8859-1"?>
<package_set>
    <name>package_set_name</name>
    <packages>
        <opkg>opkg1_name</opkg>
        <opkg>other_opkg</opkg>
    </packages>
</package_set>

Default Package Set

OSCAR currently supports only one package set: the “Default” package set. This package set defines the set of OPKG(s) that are available, by default, in OSCAR for a specific Linux distribution. For instance, the default package set for Debian Etch x86_64 is (filename: [source:trunk/share/package_sets/Default/debian-4-x86_64.xml debian-4-x86_64.xml]) :

<?xml version="1.0" encoding="ISO-8859-1"?>
<package_set>
    <name>Default</name>
    <packages>
        <opkg>base</opkg>
        <opkg>c3</opkg>
        <opkg>oda</opkg>
        <opkg>rapt</opkg>
        <opkg>sc3</opkg>
        <opkg>sis</opkg>
        <opkg>yume</opkg>
    </packages>
</package_set>

The default package set is parsed by $(OSCAR_HOME)/scripts/package_config_xmls_to_database.
