It would apprear that ACE is essentially completely undocumented which is very annoying. The code can be found here: https://github.com/puppetlabs/ace
ACE is managed by this profile
Request for docs is here: https://tickets.puppetlabs.com/browse/DOCUMENT-1237
Definitely not covered.
TBH I don't even really khttps://puppet-kmo.gitbook.io/pe-deploy-and-discover/-Mi21RNRmfAP7onT0Kyl/now what ACE does properly so I have no clue what we need to know about it
