# UGLY... but we have to semi hard coded them... since live helper won't work in Ubuntu if we do not assign version number. It's because the kernel package name in Ubuntu is like linux-image-2.6.24-7-generic, and if we do not assign version number, live-helper will try to install linux-image-2.6-generic, which does not exist in ubuntu. In Ubuntu, it's linux-image-generic.
