I have in mind creating some other interfaces that will be on a par with serial for early boot availability. So lets not frame this in terms of eth vs serial. We can throw a priority int in the config interface, stuff that in the plug struct, and pick whichever one's highest and claims to be currently available. -- Matt Mackall : http://www.selenic.com : Linux development and consulting - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/ | ||||||||||||
