Comment 4 Kamil Páral 2012-09-05 08:30:56 UTC
I see this alert when doing a system installation from Fedora 18 Alpha TC5 Live GNOME i686. After the installation has finished, this was in the list of alerts.

Proposing as Final blocker. Our criteria only speaks about installed system boot, not about selinux alerts during installation. I don't know whether it applies:
" In most cases, there must be no SELinux 'AVC: denied' messages or abrt crash notifications on initial boot and subsequent login (see Blocker_Bug_FAQ) "

We should either fix the alert or disable SELinux troubleshooter when Live is run, so that the users are not bothered with cryptic messages.

Comment 5 Miroslav Grepl 2012-09-06 11:46:09 UTC
could you attach raw AVC msgs from the /var/log/audit/audit.log for all your bugs related to Alpha TC5 Live?

Comment 6 Miroslav Grepl 2012-09-06 12:09:23 UTC
I am interested in syscall field.

Comment 7 Kamil Páral 2012-09-07 12:37:25 UTC
I used Alpha TC6 Live, but it seems to behave exactly same. Here is the excerpt from audit.log:

So old F18 policy. The latest F18 policy build should be used.
