What it does is it exposes a Mach device as a filesystem node (hence
"devnode"), so you can do open("/dev/foobar") instead of
device_open("foobar"). In particular this means that the Unix
permission model can be used to manage access to the fs node, rather
than you having to have the device master port (= be root).
