So what happens if new interfaces appear on the system after the capture starts?  Could a new ILB get written that overrides the previous one (which could also be done if interfaces *disappear* after the capture starts)?  If not, that means the ILB indicates what interfaces exist at the time the capture started, but doesn't necessarily indicate what interfaces existed throughout the capture.
