To be clear here, I'm not sure why /bin/passwd was trying to access /dev/vga_arbiter, but I thought I'd go ahead and report this so that someone smarter than me could take a look. We have fix this in the latest F16 policy. You can grab this policy from koji for now http://koji.fedoraproject.org/koji/buildinfo?buildID=266002 selinux-policy-3.10.0-36.fc16 has been submitted as an update for Fedora 16. https://admin.fedoraproject.org/updates/selinux-policy-3.10.0-36.fc16 Package selinux-policy-3.10.0-36.fc16: * should fix your issue, * was pushed to the Fedora 16 testing repository, * should be available at your local mirror within two days.
