I noticed it because with the audit-viewer I cannot see the "msg=" part
of TRUSTED_APP records. I submitted a bugtraq
(https://fedorahosted.org/audit-viewer/ticket/6) for that. So, that made
me look at the ausearch results to get all the info.

Additionally, I believe there is a policy issue which caused this in the
first place...

So it looks like the architectures interpretation (-i) of the syscall is
where it differs?

Thx,
