Oops, sorry because the sha512sum command-line prints a human readable
16 chars based string

dmesg | pigz -4c | dd bs=64 skip=1 > /dev/urandom

is a far better option. Obviously, in the kernel sha512sum() provides
a binary stream not a text.

The good habits to have a basic /dev populated with those few devices
that always exist like /dev/urandom allows the seeding even before the
mount procedure.
