I just installed Bugzilla from scratch. Everything is fine, except that when I first tried to access the web page it returned a permissions error. So I changed the webservergroup value from my default group to null. Now I can get in but the strong warnings returned by checksetup.pl give me reason to ask if this was the best solution.
Since we’re here, are there any other security issues that should be considered for a new/default Bugzilla install?
