I was thinking about the installer part and wondered if there is a less
obstrusive way - like: I know I have machines in my local network (a) that
I trust and (b) that I know have good entropy. Could the installer (on
request) bring up the network and query some things like time from a time
server and entropy from a known good source? The keyboard method would
of course still be needed as many users won't have the needed local servers.
