This is true for Linux, but not for NetBSD. On NetBSD no env variables are
needed, and everything is passed as arguments using the following format:
./<script> <backend_path> <xenbus state>
Where xenbus state is either 2 or 6.
On FreeBSD I'm aiming of using the same input interface for both block and
network scripts, and it is the following:
./<script> {add/remove} <backend path>
With no env variables provided at all. So either this section is expanded,
or it is labelled as "Linux Inputs".
Roger.
