So `Sbuild.userConfig` would have to check the installed version of sbuild before it could determine whether to install the backport of autopkgtest. I think it would be unwise to incorporate that complexity into Sbuild.hs for the sake of an old release of Debian, so I've mailed a patch to Joey simply documenting the issue. """]]
