I see that this change has been adopted with the -47 version of the
policy (FC13) - that was pretty quick!

There was a suggestion for change to tor.te a while ago as well (see
tor: dac_override, dac_read_search, name_bind and net_bind_service
thread) - the new version of tor (2.x) provides dns resolution as part
of the service it runs, so it needs to bind to udp/53 and the statement:


does the trick when it is included in tor.te. Currently I do this with
patching, but it would be nice to have it as part of the policy in a
similar way it was done with openvpn.
