:*****  Plugin catchall (100. confidence) suggests  ***************************
:
:If you believe that python2.7 should be allowed open access on the urandom chr_file by default.
:Then you should report this as a bug.
:You can generate a local policy module to allow this access.
:Do
:allow this access for now by executing:
:# grep system-config-k /var/log/audit/audit.log | audit2allow -M mypol
:# semodule -i mypol.pp
