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

  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
  4. Compare the installed rpms to the payload on each disc

From the Installer perspective

  • Install all groups marked default in comps.xml
  • Install any of the available categories of groups, listed in installclasses/
    • 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).
