Hi Luke,
"sometimes" means this:
[root@test-hpc puppet]# puppetd -vt --noop
info: Retrieving plugin
err: Could not retrieve catalog from remote server: Error 400 on SERVER:
Could not find resource 'Class[Common_software]' for relationship from
'Class[Default_repositories]' on node hpc.tornado
warning: Not using cache on failed catalog
err: Could not retrieve catalog; skipping run
[root@test-hpc puppet]# vi manifests/nodes.pp
[root@test-hpc puppet]# puppetd -vt --noop
info: Retrieving plugin
err: Could not retrieve catalog from remote server: Error 400 on SERVER:
Could not find resource 'Class[Common_software]' for relationship from
'Class[Default_repositories]' on node hpc.tornado
warning: Not using cache on failed catalog
err: Could not retrieve catalog; skipping run
[root@test-hpc puppet]# puppetd -vt --noop

<cut>
This is in the test lab, in this particular case agent and server are the
same host.
Every parent class has one child '-site' class, each defined in its own
module directory, so for this example there is
modules/common_software/manifests/init.pp and
modules/common_software-site/manifests/init.pp
What do you mean by "inherit properly"?
BR,
Nikita
