Thanks for the tips! In my experiments with the default bundle so far, it seems to be set up adequately for non-interactive mode - cf-agent was able to install a package without much difficulty.
The one issue I found with the default bundle, is that it called 'dpkg -l' and parsed the entire output for the status of the package. This is quite an intensive operation (all the regex stuff probably) - and it actually bumped my idle server load up from %0.5 to around %1.5. I then changed the bundle so it actually passed the package name to dpkg -l, which results in information about only that package returned. This brought server load down to near-idle again.
