Thanks for all your answers and suggestions. So, what happens is that I want to push a file from the master to a client. But the problem is that after starting the service that reads that file, it appends one line to it, which is an authorization token.
Like this: #1 file is pushed from the master to the client: line1 line2 #2 the service starts on the client for the first time and it appends the new line (line3): line1 line2 line3 #3 if I restart puppet the file will be changed to: line1 line2 #4 the service stops working because the line 3 (authorization token) is gone. I'd really like to manage all lines in that file but the one that is added after the service is started. I hope is clear now.
