The help dump (facter --help) for the current version of Facter shows a deprecation warning next to the -p flag description.
Requested Change:
I have confirmed in the facter channel that this is misleading, and that deprecation is no longer valid. With customers contacting us regarding it, we hope that deprecation warning can be removed in coming versions until such a time as a functional replacement is offered again.
The facter --puppet argument is no longer supported in facter 4, and has been replaced with puppet facts show. I'm going to close this as won't do. See PUP-6040
