I faced some issues, that the package list from apt gets not updated and then the installation fails because the package can't be found.
I currently only know from apt, but we should ensure that for every cdist package type does a refresh of the package lists before installing a package.

__package_update_index got the --maxage <seconds>-parameter (for apt) w/ commit 4d4d76bb38.
With --maxage 3600 the apt-get update only runs if the last update was at least 1 hour ago.

For the specific issue: Updating the package cache introduces
a) longer runtimes for cdist
b) increased network-traffic and
c) more dependencies on external network
Depending on the interval cdist is running this executed the impact of this varies.
CFEngine has the concept of time and thus the ability to allow things like "update the package cache if it is older than X". For apt I did a hack by adding an optional parameter --maxage N to __package_upate_index to reduce the impact.

A pre/post stage would be great though :)

My opinion is that we need to introduce something like a "pre" and "post" stage in cdist - @asteven and I discussed this briefly before - do you have the notes, @asteven?
