Warning
When running munki-promoter (versions 2.0 and later) for the first time, you will notice that the first run against your repo may attempt to promote things that shouldn't be eligible for promotion yet.
This is due to munki-promoter not "knowing" how long an item has been in a catalog beyond its initial import date.
You can work around this by using one of the following provided Command-line Arguments:
--reset-edit-date, --set-unknown-edit-date, --days-before-current-catalog
The smoothest option if you have static promotion rules is to use --days-before-current-catalog. If you know items get promoted to staging 7 days after creation, this command can infer that items in staging have been "last edited" 7 days after creation.
