Hi,
I recently had to do some selinux tuning to have chrome correctly start on my fedora 20 box. I googled around and eventually found the correct type to apply to the chrome executable in order to make it work.
So the problem is solved, but the error messages that I got were much less informative than I expected. After watching https://www.youtube.com/watch?v=MxjenQ31b70 on selinux configuration, I was expecting messages in a format like "selinux is preventing X from access on directoy Y", but instead...
'journal -f' provided nothing useful; 'tail -f /var/log/audit/audit.log' showed a couple of log lines which actually mentioned chrome, but in too generic a manner (see below):
--------------------------------------

--------------------------------------
Before I fixed the problem, launching google-chrome from command line resulted in an error message about the impossibility of creating directory .pki/nssdb in my home. No mention of this directory name in the audit.
And to finish, the SELinux troubleshooting tool didn't show anything at all.
Why don't I see a richer diagnostics? Am I missing some configuration?
Kind regards,
