I ran across this article that does a good job of explaining the differences
between VL-Hot and HAL (used for autodetection of removable devices.) It also
very clearly states that a limitation of VL-Hot is that it can not automount an
inserted CD like HAL can. I know this was a problem we ran into at the
warehouse. The author states that the extra polling that HAL does in order to
be able to automount a CD creates a noticable burden on the system. I have my
doubts that even on the older P3s we're using this would be noticable.
Regardless, I think the minimal cpu hit from HAL is worth not having to train
users how to mount a CD before they can open it.
Tony
