Issue #3806 has been updated by Dan Bode.

after discussing this with Trevor, I think the only type of resource action 
that would need to be tracked are pending refresh actions. Everything else 
should be able to resolve correctly just with another puppet run.

Feature #3806: Atomic Puppet

Per the mailing  list:

I thought I'd toss this idea out here to get pointed and laughed at
before I Redmine'd it.

I ran into the fun situation recently where I needed puppet to be more
atomic.

Basically:

(A) Update file -> (B) Restart Service

But...for some reason puppet got interrupted precisely between A and B!

So, the next time puppet ran, my system wasn't in the state that I had
described, instead the file had been updated but the service had not
been triggered.

This got me thinking about the concept of atomic puppet updates. It
shouldn't be too difficult to write to disk/register the state of the
operations as they happen and to be able to pick back up by default if a
run is interrupted.

I say this, of course, completely tongue-in-cheek as the last graph
discussion I jumped into went on for tons of messages!
