How are things? I really enjoyed the conference. It looks like I'll be volunteering there next year (march 15-16, 2013) so if I don't make it down to Seattle within the year, I'll definitely be down next year. I would love to grab that beer. Shoot me an email (rt at this domain) sometime and we can try to organize something. Toraton!

I've been learning more about cfengine since I originally posted this and the subtlety you describe has become clear to me. I definitely appreciate it being pointed out here for anyone that finds this post and attempts to understand interation based on my description.. Clarity and correctness FTW! Thanks for the comment, Nick!

They are functionally interchangeable. However I believe they express slightly different intensions. Its hinted if you look at the bundles in the stdlib. append_if_no_line takes a str, and append_if_no_lines takes a list. Again, these are just names, nothing enforces that you pass a variable of that type to them, but it makes a difference on how the edits happen. You are doing implicit looping over the slist at the files promiser level, so its effectively n file promises where n is the number of list elements you have. When you run your policy you should be able to see this happen where the file is edited multiple times instead of once. If you actually pass the list into the append_if_no_lines bundle the implicit lopping happens inside the append_if_no_lines bundle and you only see a single file edit but each line is iterated over and added. Its a subtle difference and there should probably be some comments in the stdlib hinting at that difference since they are functionally interchangeable. I posted a gist that shows the difference while running as well as the policy. (notice how /tmp/test1 is edited once, and /tmp/test2 is edited 3 times) https://gist.github.com/2124224 I think there is a small disconnect in whats happening here.

But the main thing with self hosted bloggin' is to be free to do as one like and never regret! Also I see posts focused on a niche and without discussing in detail a specific problem there's no way to get real feedback (+1, FB likes or plain tweets doesn't counts for me!) Anyway keep going man! Today you've earned a reader ;-) Well, 3.5 posts a months is too few to build a real following ‘mass’ audience.

This is excellent. Use Skype a lot and don't want to be caught out when stuffing my face with food or something else. ;p Thank you!
