I've just encountered a problem starting tor. When I do 'systemctl start tor' it fails and I get selinux errors in the log. There was suggestion to do full auditing with 'auditctl -w /etc/shadow -p w'. Which I did and it gave the following

So I had a look at the permissions for /var/lib/tor/hidden_service/ and they were
drwx------. toranon toranon system_u:object_r:tor_var_lib_t:s0 hidden_service
Still trying to figure out this selinux issue :(
Perhaps somebody could point me to the best mailing list/forum/tracker for this kind of issue?
Most likely this is tor running as root and trying to access this file.
