Comment 1 Miroslav Grepl 2011-03-11 12:27:05 UTC
How Dan said, we should fix it on non mls machines.

Comment 2 Daniel Walsh 2011-03-11 13:10:00 UTC
Yes fprintd should not be installed on MLS boxes.

We have this policy in F15

Comment 3 Miroslav Grepl 2011-03-17 10:27:30 UTC
Fixed in selinux-policy-3.7.19-79.el6
