As DJB pointed out on another listhost, one only needs 256 random bits
once, and can then use a PRF to generate an indefinite number forever.
Why does /dev/random not do this and so avoid blocking after startup?
It wouldn't be that hard to write to a defined block of a disk image
these 32 random bytes.
Sincerely,
Watson Ladd
