This change documents how you need to use exec in run hooks to avoid bad behavior, as well as providing a simple example and suggestions on when you would want to use a run hook instead of
$pkg_svc_run
. Let me know if the reasons to use a run hook are incorrect and you could do those using$pkg_svc_run
instead.I also fixed a couple of links pointing to the hooks section.
This fixes #989
