dd advanced example

Regarding dd - advanced example

Since only relatively few random numbers are required for the seed, why don't we recommend /dev/random instead of /dev/urandom and also bs=256 instead of 128 ?

I've reworded it a little, so that it does not sound like a "recommendation". For the u/random part, my first thought is that it really depends on your system and usage. A lot of users may use such procedure from an installation ISO, i.e. there may not be a full random pool. In such case one might not want to use it up for something like a disk wipe, when it may be more important to have the best quality pool for other purposes. --Indigo (talk) 19:30, 29 March 2017 (UTC)
