These results were generated with Rangefinder, a tool that helps predict the downstream impact of breaking changes to elements used in Puppet modules. You can run this on the command line to get a full report.

Exact matches are those that we can positively identify via namespace and the declaring modules' metadata. Non-namespaced items, such as Puppet 3.x functions, will always be reported as near matches only.

Hi @jordi-upc, this is change that we are happy to merge. However, we want to point out that this is only a compatibility change as we do not currently support Raspbian. I will make a small adjustment to the PR title before merging just to avoid any confusion about that topic.

Thanks for your contribution! 👍
