[arch-general] /etc/libvirt/qemu/network/default.xml.pacnew permission change?

All, The original /etc/libvirt/qemu/network/default.xml has 0600 permissions, the new /etc/libvirt/qemu/network/default.xml.pacnew installs with 0644, is there any significance to the permission change or does the .pacnew just need to be put in place with 0600? (or does it matter?) -- David C. Rankin, J.D.,P.E.
