- <para>The packages used during the build process, by default, are
- downloaded from the current PlanetLab Central boot server. To change
- this, the file yum.conf, in the checked out bootcd_v3 directory, will
- need to be modified. The yumgroups.xml file, also located in the same
- directory, is used by the build process to identify which packages
- should be placed on the resultant cd image. This file should be located
- in one of the yum rpm repositories specified in yum.conf.</para>
