If you use a normal pseudo random number generator and print the seed (e.g. create from the time) initially the image can be easily recreated later without shipping it around. /dev/urandom is not really needed for this since you don't need cryptographic strength randomness. Besides urandom data is precious and it's a pity to use it up needlessly. bash has $RANDOM built in for this purpose. -Andi - To unsubscribe from this list: send the line "unsubscribe linux-ext4" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html
