Calling /proc/uptime with /etc/init.d/rcS may not correctly deliver your boot time. Some processes might still be starting after you cat /proc/uptime I also wonder why you have an idle time of 0.38 seconds. During boot there should hardly be any idle time. You could write yourself an init script and make sure it is the last one to be called by rc. Also note that the uptime delivered by the kernel may not be accurate enough to measure a system's boot time (e.g. pre-kernel hardware calls, etc.). //A yeti -- To unsubscribe from this list: send the line "unsubscribe linux-newbie" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.linux-learn.org/faqs
