Puppet users - Nov 2010 - quick question on declaring variables in nodes with 2.6.2

Hi all,

I run the test.pp on the master host and the notify supplies the correct  
variables in the class notify and define notify.
node default {
$puppet_master = "hitw-cn-master-1"
include cn
}
node f13guest inherits default {
include test
test::thistest{"aname":}
}

notify{"outside class: $puppet_master":}
class test {
notify {"In class: $puppet_master":}
define thistest {
notify {"In define: $puppet_master":}
}
} #end class

notice: In class: hitw-cn-master-1
notice: //test/Notify[In class: hitw-cn-master-1]/message:  
defined ''message'' as ''In class:
hitw-cn-master-1''
notice: outside class:
notice: //Notify[outside class: ]/message: defined ''message''
as ''outside
class: ''
notice: In define: hitw-cn-master-1
notice: //Node [f13gues]/Test::Thistest[aname]/Notify[In define:  
hitw-cn-master-1]/message: defined ''message'' as ''In
define:
hitw-cn-master-1''


When I use the same idea in the yumrepo class
node ''hitw-gc-web01'' inherits gdn_default_web {
include yum
$puppet_master = "hitw-gc-master-1"
}

class yum {

notify{"puppet master is: $puppet_master":}

case $operatingsystem {
redhat: { $yum_packagelist =  
[ "yum", "yum-utils", "yum-plugin-fastestmirror" ]
}
centos: { $yum_packagelist = [ "yum", "yum-utils",
"yum-fastestmirror" ] }
fedora: { $yum_packagelist =  
[ "yum", "yum-utils", "yum-plugin-fastestmirror" ]
}
}

package { $yum_packagelist: ensure => installed }

}
yumrepo { "utils":
baseurl => "http://$puppet_master/cblr/repo_mirror/utils",
descr => "Puppet related utilities repo",
enabled => 0,
gpgcheck => 0,
}
}

notice: /Stage[main]/Yum/Yumrepo[utils]/baseurl: is  
http://hitw-gc-master-2/cblr/repo_mirror/utils, should be  
http:///cblr/repo_mirror/utils (noop)
notice: /Stage[main]/Yum/Notify[puppet master is: ]/message: is absent,  
should be puppet master is: (noop)

Apart from the node declaration (declaring in the inherited node as opposed  
to the node itself) the concept is the same.

What am I missing?

Cheers,
Den

Variables in the parent node are *not* visible in the child node when you use
inheritance.  Seems crazy, I know, but there you have it.

I''m generally not a fan of node inheritance. There are usually other
approaches that are more easily built and debugged.
