I think that (perhaps optionally) allowing the user to specify their own UUIDs would be a good idea; whatever was generating the script being executed might have access to a better entropy source. > However,I wonder how can we provide better GUID (and in general random > numbers pool) generator for u-boot. > > Maybe md5sum command can be used with some running clock (WDT, or > system clock from u-boot start up) data to provide better entropy? If there's a standard way of retrieving wall-clock, MAC address, ... it'd definitely be a good idea to include those entropy sources. _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
