2. Cfkey reference
The very first thing you should do on every host is to establish a
public-private key pair. To do this, you need to run the program
on every host. This program needs to produce random numbers, and needs a
source of randomness. A good strategy is to install and run the
`cfenvd' program for a week or two in advance of deploying cfengine
2, since `cfenvd' collects random events, which are an excellent source
of entropy for random number generation.
If you get the error message "PRNG not seeded", it means that insufficient
data were found in order to make a random key. In that case, run `cfenvd'
for a few days more and try again.
