[Pkg-puppet-devel] Puppet 4 (stretch) Master with 3 (jessie) agents?

[Wilmer van der Gaast]

Hello,

I *hope* this is a reasonable place to ask this question:

While upgrading my (tiny) fleet, bit by bit, I had some issues getting
that combination going. But I read the following bit in NEWS.Debian:

"""
  The Ruby Puppet master as shipped in Debian can currently handle
Puppet 3.x clients only when run under a rack-enabled web server. If you
are using the standalone (WEBrick) puppet master from the puppetmaster
package and want to support Puppet 3.x clients, please switch to using
puppet-master-passenger instead.

  As always, you should upgrade the Puppet master first, and the clients
afterwards. Puppet 4.x clients will not work against a Puppet 3.x master.

"""

Timestamp looked recent, but ... this info contradicts what I see
elsewhere (where Puppetserver, not in Debian from what I can tell, is
the only thing backward compatible), and indeed now that I've finally
migrated my master to use passenger, I'm still getting the same issues
on v3 agents.

Is this as expected and should the NEWS be removed? And what's the
most-used solution, installing puppet from jessie-backports on old
machines for now?

(Given what I've read about parser/facts incompatibility, I suppose
that's not a terrible idea anyway...)


Kind regards,

Wilmer van der Gaast.
