Okay, so looks like i picked a bad example. Thank you for your informative 
stuff: "exists?" must return either "absent" or "present".
But.. what about create routines then?
What's the internal flow ? something like:
* puppet calls exists?
* if it returns absent, call create
* puppet calls exists? again to verify
* puppet decides what message to log?
