I believe the installer adds it when it decides that you have only a
serial console. Did you do the install through serial?
Yes. For the JS2X blades you have to do all work thorough the serial
connection. I can see where this can be logical to do. But at least in
this case it is causing nothing but problems. Since the kernel can auto
detect it there really is no reason to have this anymore (but I'm trying
to see if anyone knows something I don't about some ancient machine or
something where this is absolutely needed).
