The change you are proposing here only touches unprivileged libvirtd when it creates $XDG_RUNTIME_DIR/libvirt. Furthermore the change you are proposing is a security flaw, since the $XDG_RUNTIME_DIR/libvirt directory is *only* intended to be accessed by the current unprivileged user. Using a umask of 022 lets it be accessible to any user. So NACK to this Daniel -- |: http://berrange.com -o- http://www.flickr.com/photos/dberrange/ :| |: http://libvirt.org -o- http://virt-manager.org :| |: http://autobuild.org -o- http://search.cpan.org/~danberr/ :| |: http://entangle-photo.org -o- http://live.gnome.org/gtk-vnc :| -- libvir-list mailing list libvir-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/libvir-list
