This is a feature.

For now, kickstart the device with

# ${SOME_COMMAND} > /dev/random

SOME_COMMAND should have output entropy proportional to the seriousness
of your threat model. For messing around at home, 'ls -alR /etc /var' is
probably OK.

Something like 'echo foo' will work, but will start your RNG in a known
insecure state.
