openswan start denied by selinux if a custom log file is used

Hello

     I am using CentOS 6.4 and I want to store the logs from openswan 
into a different file ( /var/log/ipsec ) than the default. For this 
purpose I added

    plutostderrlog=/var/log/ipsec

to ipsec.conf.
     As long as I keep the server in permissive mode, openswan starts 
OK. If, however, I switch to enforcing, the daemon refuses to start with 
the following error message displayed in the console:

    ipsec_setup: Starting Openswan IPsec
    U2.6.32/K3.0.78-1.el6.elrepo.x86_64...
    ipsec_setup: Cannot write to "/var/log/ipsec".

     The audit log does not record anything useful so I tried to switch 
dontaudit to off and see if anything useful comes out. After running 
audit2allow and a bit of trial and error I came out with the following 
custom policy :

    module myipsec 1.0;

    require {
             type ipsec_t;
             type var_log_t;
             class file { write ioctl getattr append };
    }

    #============= ipsec_mgmt_t ==============

    allow ipsec_mgmt_t var_log_t:file write;


     The above policy worked for me but I am wondering if it is OK (I am 
mostly confused by the fact that the class includes " write ioctl 
getattr append " but the rule has only "write" ). And, assuming it is OK 
can this custom policy ( or the corrected one if needed ) be included in 
the default policy ?

     TIA

         manuel
