I found that I always got the same fortune quote after reboot, over and over 
again. It means that /dev/random produce exact the same values after reboot.
It means that machine timer or keyboard not used for enthropy gathering.
Using keyboard alone not helps for automatic tasks because it can be even not 
present, so machine timer must be used at least after reboot stage i.e. in 
randomdev init procedure. Otherwise first random values are very predictable 
and subject for attack.
