Realistically speaking, a random UUID is probably the best you're going to ever get. I highly suspect that any time- and MAC-address-based solution is going to suffer from mis-set clocks and misprogrammed MAC addresses more often than you will have collisions in a 122-bit random number. -hpa - 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/ | ||||||||||
