A possible issue though might be lack of enough entropy to make
/dev/urandom results unpredictable, since the system is just being
initialized and entropy collection is not likely to have occurred much. 
To be non-blocking, it would then fall back to generate results similar
to random(3) if necessary, I believe ("degenerates to a pseudo-random
generator").  Of course this might only matter to some extent depending
on your use of CGD
