I apologize if this is the wrong spot. I can't figure out where to go.

atd fails beginning in kernel 3.6.0 reporting 'Can't link execution file: Operation not permitted'

1) atd works in kernel 3.5.5
2) A version built from the latest source in 3.6.1 fails in the same way

Find the strace log below. I don't understand it. The reported error seems to happen at:

	link("a0000101574742", "=0000101574742") = -1 EPERM (Operation not permitted)

In 3.5.5, when atd works, the end of the trace changes at the first getdents; the link never happens:
