The post_s390_snippet is enabled by default in all current Beaker kickstarts, but: 1. A comment in the kickstart claims the issue it deals with was fixed in RHEL5-U3 2. The documentation claims the snippet is broken (http://beaker-project.org/docs/admin-guide/kickstarts.html#kickstart-snippets) If the comment is accurate, the kickstarts for Fedora and more recent versions of RHEL should not load the snippet. If the docs are accurate (which seems unlikely, given that s390 provisioning currently works), then the snippet shouldn't be loaded at all. If either the docs or the comment are inaccurate, then they should be fixed :)
