standard.livebuild is a tar'ed directory containing the configuration and package lists to drive live-build

edit existing config/package-lists/*.list.chroot or add new ones to add new packages to the build.

livebuild_pre_run can be used to modify the live-build command line parameters on-the-fly via the OBS editor and to apply other fixes and workarounds, it will be executed by the obs-build recipe before starting the build
