To clarify my point, I forgot to mention something.

This setting is not about changing any existing function behavior or
how a given argument (using one of the dozen constants) behave, nor
what a given argument will use as source. Each argument defines an
entropy source which fits in one of the two propose settings. That's
why these settings only allow one to define what will be used instead
of hardcode /dev/random, /dev/urandom or /dev/arandom. Especially for
the implementations where only one is used without any chance to work
around it (besides ugly symlink and the likes).
