Package Ordering

Some notes on how package ordering should work. These notes attempt to use the least amount of discs in case a Next, Next, Finish type installation is performed.

The Problem

Installing Fedora 10 from CD media uses 5 discs for a "default" installation (Next, Next, Finish)

Troubleshooting

1. Install Fedora 10 from a DVD using Next, Next, Finish
2. Grab the install.log from /root/
3. Grab rpm -qa --qf="%{NAME}.%{ARCH}\n" for comparison (Attached: File:PackageOrdering-Fedora10-Rpm-name.arch.log)
4. Compare the installed rpms to the payload on each disc

From the Installer perspective

• Install all groups marked default in comps.xml
  • Use scripts/find-default-groups.py to discover which groups are marked as default
• Install any of the available categories of groups, listed in installclasses/fedora.py
  • These categories contain lists of groups to be added to the installation
• Customize the installation

The Selection of Packages from Groups

• From the groups selected, default packages are selected.
  • Optional packages from the group may have been pulled in, which appear as "unselected" in the group.

Default packages from default groups are selected when a Next, Next, Finish type installation is performed

In Python Code

1. Get the comps groups from yum.comps.groups
2. Iterate the groups and get the default groups, the non-default groups, and the non-default @*-support groups
   1. In comps.xml, some groups are marked <default>true</default>, others are marked <default>True</default>. Note that the former doesn't allow itself to be compared in Python if statements, and you need to bool(group.default).
