Hi!
This appears to be another reason for sysvinit or any other init system
that actually uses the seed file to let the kernel start with enough
entropy:
Daniel Lange: Openssh taking minutes to become available, booting takes
half an hour ... because your server waits for a few bytes of randomness

I do understand the concern when booting from hundreds identical images,
but when creating images, you'd better delete OpenSSH host keys, seed
file and so on.
I consider getting a chaoskey. :)
