As you mentioned, NODEVICE contains ALL "nooptions" and "nod= evice" and ADDON contains some extra options not contained in GENERIC. GENERIC is a symbolic= link to the original GENERIC in the appropriate sys folder. Thanks to FReeBSD's sophisticated kernel configuration, this hierarchical s= cheme prevents most accidents triggered by significant GENERIC changes. Do you suspect a misconfiguration due to uncaught changes in GENERIC?=20 --=20 O. Hartmann
