+# Build PlanetLab-Bootstrap.tar.bz2, the reference image for PlanetLab
+# nodes. Requires the web and boot servers to be up, which complicates
+# bootstrap. Alternatively, we could require the build server to host
+# a local yum repository. Already, it is required to run the same
+# major version of yum as the nodes.
