At eclipse.org we wanted all git repositories to disallow non-fastforward commits by default. So, we set receive.denyNonFastForwards=true as a system configuration setting. However, this does not prevent a non-fastforward force push. If we set the same configuration setting in the local repository configuration then it does prevent non-fastforward pushes. For all the details see this bugzilla, particularly comment #59 where we finally narrowed this down: https://bugs.eclipse.org/bugs/show_bug.cgi?id=343150 This is on git version 1.7.4.1. The Git book recommends setting this property at the system level: http://git-scm.com/book/ch7-1.html (near the bottom) Can someone confirm if this is intended behaviour or not. We ended up using a script to set a local config property in each repository, but with several hundred git repositories it would be much easier if the system setting was honoured.
