I think that having devfs creating its own device would be nice thing for this purpose... i.e., just stat "/dev/devfs" to check if devfs is running. As an added bonus, devfs operations can be added by reading, writing, or ioctl'ing this device. this can work if you need to check whether devfs is running _now_, as opposed to knowing whether it is compiled into the kernel. Julian, your comments?
