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