Hi Brian, hi Aleksey!

this handle slide doesn't help me.

<< CFEngine will tell you the handle of each promise in the debug output. >>

Great thing, but what for? I could grep for the bundle name or comment.

<< By giving each promise a unique handle you can swiftly jump back and forth between your debug output and your policy file.>>

What do you mean by that "jump back and forth", I assume the same one can do by using grep for the bundle-name or comment?

Searching through all threads there is something Mark Burgess wrote in 2010 about handles: that they are just (able to get) used in Nova for tracking dependencies. 

If I use comments and depends_on.. what reason could be left to use handles with Core?

Thanks so much!

Have great weekends,

Chris

You can grep for a comment. But usually handles are shorter.

Yes you can. A bundle contains multiple promises so it won't get you as
close as looking for a handle or a comment.

depends_on depends on the use of handles. So you must use handles if you
are using the depends_on attribute.

That makes sense.

Makes sense, too.

Thanks Nick =)
