The issue has to be fixed by Red Hat, they are the ones that created the problem they have to fix it we can't. you could package libtalloc2 to not conflict at all with rhel and allow rhels package to be installed and work fine. in the instance of rhel doing something that makes a package not work in epel and there is no way to package things so that they can all live happily and work we have to remove the package from epel and send an email to the announce list stating so and why. This is one of the pain points in having Red Hat go off and do its own thing and not considering us. we can only work as much magic as we can to make things work. Dennis
