After installing the updated bind package for bug 8304, using mgaapplet, I noticed that /var/lib/named/etc/named.conf.rpmnew was created, but I was not given the option after the installation, to inspect the changes. If I'm reading the code correctly, the problem appears to be /usr/lib/perl5/vendor_perl/5.14.2/Rpmdrake/pkg.pm, line 877, where it's limiting the search to packages where the path starts with /etc, instead of looking for packages where the path contains /etc/.
Fixed in SVN for cauldron & mga2
