Also, because the API changed, that means it has a soname number change, which means you will need to recompile everything that links with libaudit. So, it would only be needed for new linux distributions, which should be using a recent kernel. If you have an older distribution and kernel, use 1.7.17 instead. Fedora 11, for example, uses it. But since Fedora 12 is new, it uses the 2.0.x series. -Steve
