Bug 684521

+++ This bug was initially created as a clone of Bug 637613 +++


Summary:

SELinux is preventing /usr/bin/runcon "transition" access on /bin/mount.

Detailed Description:

SELinux denied access requested by runcon. It is not expected that this access
is required by runcon and this access may signal an intrusion attempt. It is
also possible that the specific version or configuration of the application is
causing it to require additional access.

Allowing Access:

You can generate a local policy module to allow this access - see FAQ
(http://docs.fedoraproject.org/selinux-faq-fc5/#id2961385) Please file a bug
report.

Why are you using runcon to run mount as unconfined_t.  This is not supported.

It also looks like you might have a labeling problem.  Your init script should not be running as init_t but as initrc_t.

You might want to run 

restorecon -R -v /etc

Or relabel the entire system

fixfiles restore

I have no idea. The fact is: I made a fresh install of Fedora 13 and then I tried to install the ATI Graphics Driver, I think it made SELinux signal that problem.
My card is ATI Radeon HD 4350. Hope that helps.

Thanks

Leon fix the labelling and I think you will be ok.

What is "labelling" and how do I fix it?
Thanks

SELinux is a system that puts labels on every file on your disk.  Sometimes the labeling can get screwed up.  The safest way to relabel the file system is to login as root and execute

# touch /.autorelabel; reboot

This could take a decent amount of time, depending on how large your system is.
You should not need to do this again.  I have no idea how your system got mislabeled.
