Actual results: Expected results: Additional info:
Dan, Autofs has an option for supporting a random multimount selection scheme. Because of this, we seed the random function with /dev/random at daemon startup. So, can you modify the policy accordingly? Should this be reassigned to policy?
Fixed in selinux-policy-2.5.8-8.fc7
