Sure, and I've acknowledged that. But it doesn't mean this needs a kernel solution. > I want a dynamic /dev, but a fast one that doesn't need initrd or > slows down booting. So use Eric/Arjan's program that does it in 60ms -- you get a dynamic /dev, no initrd, fast boot, and no kernel changes required. It remains to be seen how much it costs to do it in user space vs kernel space. Arjan -- do you have a pointer to your program? Perhaps I can shake loose some time to test that. -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
