Actually it says you need to set up a source of randomness /so that/
rndc-confgen will work in a reasonable amount of time.

Take a look at rndcontrol(8) and then at the output of 

    vmstat -i

so that you can choose two or three interrupts that occur relatively
frequently and enable those as feeds for the entropy source.  Nb.
don't try enabling the clk or rtc interrupts for this purpose: those
tick at regular intervals, and the whole point is to exploit the
random spacing between interrupts.  Use rndcontrol(8) to turn on the
entropy harvesting, and then leave the system to work for a while and
gather a bit of entropy.  After that rndc-confgen(8) should work fine.

	Cheers,
