It didn't help - there just isn't enough entropy data being generated
between boot time and when I extract the random numbers. This is
basically a system to install a linux distribution, so it's booted off the
network with a readonly root NFS, so there is no saved entropy data to
load, so I'm starting off with an empty entropy pool and having to rely on
the kernel to generate the data from scratch. The random numbers are used
to initialise the ssh and VPN keys.
