Based on the following question:

# zypper refresh
# zypper install puppet

Run a custom fact based on core facts

So what if my previous example puppet custom fact easy as 1 2 3, needs to be run only on RedHat systems?

An additional line on the ruby file is added:

Facter.add('netuuid') do
   confine :operatingsystem => "RedHat"
   setcode do
      Facter::Core::Execution.exec("echo `grep UUID /etc/sysconfig/network-scripts/ifcfg-eth0 | cut -c 7-42`")
   end
end

Any core fact can be referenced with the colon and name of the fact
:operatingsystem
:osfamily
:kernel
etc.

Proper puppet variable declaration

The problem:

Error: Could not retrieve catalog from remote server: Error 400 on SERVER: Syntax error at ','; expected '}' 

Wrong variable declaration:

class repos::params {
      $baseurl = "foo",
      $baseurl_key = "ha",
      $sles12_baseurl = "doo",
      $sles12_SDK_baseurl = "ken",
}


Proper variable declaration:

class repos::params {
      $baseurl = "foo"
      $baseurl_key = "ha"
      $sles12_baseurl = "doo"
      $sles12_SDK_baseurl = "ken"
}

SLES12 and puppet agent

I found close to no documentation on getting the puppet agent running on SLES 12.

What worked for me was the following repository and then only a zypper install puppet.

That's pretty much it.
