I can see why you would suggest console.perms as the place to look
for a solution to this problem. But:
1. I can find no reference to /dev/null in console.perm related
2. We have ~50 machines with the same copnfiguration of
console.perms and do not have the same problem.

If anyone has further assistance on where to look I would appreciate
