Thanks a lot !

1- How may i suggest/learn to add this info in the random generator man 
page, so that a search in doc gives the right result ?

2- As / will be mounted read-only, how can i tell the ramdom generator 
to put this /entropy file somewhere in /var, where i think it should be 
? Or is there any tricky hidden problem ?

Thanks a lot,
