[Fedora-packaging] rpmlint non-standard-[ug]id, non-standard-dir-perm

I'm packaging cricket and rpmlint complains: cricket.noarch: W: non-standard-uid /etc/cricket/config/Defaults cricket cricket.noarch: W: non-standard-gid /etc/cricket/config/Defaults apache cricket.noarch: W: non-standard-uid /etc/cricket/config cricket cricket.noarch: W: non-standard-gid /etc/cricket/config apache cricket.noarch: E: non-standard-dir-perm /etc/cricket/config 0771 cricket.noarch: W: non-standard-uid /etc/cricket cricket cricket.noarch: W: non-standard-gid /etc/cricket apache cricket.noarch: E: non-standard-dir-perm /etc/cricket 0771 cricket.noarch: W: non-standard-uid /etc/cricket/cricket-conf.pl cricket cricket.noarch: W: non-standard-gid /etc/cricket/cricket-conf.pl apache cricket.noarch: W: non-standard-gid /var/log/cricket cricket cricket.noarch: E: non-standard-dir-perm /var/log/cricket 0775 cricket.noarch: W: non-standard-uid /etc/cricket/subtree-sets cricket cricket.noarch: W: non-standard-gid /etc/cricket/subtree-sets apache cricket.noarch: W: non-standard-uid /var/cache/cricket apache cricket.noarch: W: non-standard-gid /var/cache/cricket cricket cricket.noarch: W: non-standard-gid /var/lib/cricket cricket cricket.noarch: E: non-standard-dir-perm /var/lib/cricket 0775 What is the rationale for these warnings and errors, and why should the package avoid using them?
