Dear all

I'm really a newbie in using cfengine. I'v do som policy to configure a 
server, and learning with errors and corrections. I managed to install some 
services, maybe not in a "elegant" way at this moment, but funcionally.

Right now, i'm facing the need to modify a YAML file from some value. For 
example, change the following line:
ipaddr: 10.0.0.1 
with 
ipaddr: 172.16.1.1

I could get back in a policy test file the line of this ipaddr, with the 
readyaml funtion. But i could not foud how to write off this new values 
inside the original file.

I' could use a copy function to copy the correct file, and it's funcional. 
But requiee that i put this good file in a specific repository. 
It's my next step of learning this great automation system that is Cfengine.

Regards!
