Strange setroubleshoot report.



SELinux is preventing /usr/lib64/chromium-browser/nacl_helper_bootstrap from search access on the directory 3.

*****  Plugin catchall (100. confidence) suggests  ***************************

If nacl_helper_bootstrap는 디폴트로 3 directory에서 search 액세스를 허용해야 합니다. 
Then 이 버그를 보고해야 합니다. 
이러한 액세스를 허용하기 위해 로컬 정채 모듈을 생성할 수 있습니다. 
Do
지금 이 액세스를 허용하려면 다음을 실행합니다: 
# grep nacl_helper_boo /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp

Did anything actually break or did you just see the AVC reported?

I just added this to F18.
