Puppet users - Feb 2011 - Using Ruby DSL requires master restart for unrelated changes?

There''s an open bug a few months old that states that changes to Ruby
DSL manifests require a puppetmaster restart: (
http://projects.puppetlabs.com/issues/5256
).  I can actually live with that, as I only plan on defining a couple
of small key things that won''t change often in Ruby DSL and leaving
the rest to normal puppet manifests.  However, the problem I''m
experiencing w/ 2.6.1 (Ubuntu Maverick''s official packages) is that
having a Ruby DSL manifest seems to require puppetmaster restart on
*any* change anywhere, even completely unrelated .erb templates or
manifests.

The basic setup I''m trying is this (the idea is to define some
variables at the hostclass scope via ruby):

manifests/rf.rb:
hostclass :rfbase do
    scope.setvar(''rf'',''test123'')
end

manifests/site.pp:
import "rf.rb"
[...]

And then my hostclass inherits this:
class some_specific_class inherits rfbase { .... }

Basically, everything works perfectly on a fresh restart of
puppetmaster.  But if I so much as "touch /etc/puppet/manifests/
unrelated.pp", or even touch a random .erb template, everything falls
apart.  Restarting puppetmaster fixes it again.  The failures look
like this on the client:

err: Could not find parent resource type ''rfbase'' of type
hostclass in
production at /etc/puppet/manifests/node_classes.pp:2 on node
lb01.use.snpriv

Anyone have any ideas about this?  I feel like there must be some
stupid answer for this, either that or nobody out there is using Ruby
DSL, because this renders it pretty unusable...

Hi,

I have never dabbled in Ruby manifests.

Still, could you try with anything at least as recent as 2.6.3? I''ve
read that early 2.6 was a bug-ridden beast.

Felix

Yes, that fixed it.  I switched my puppetmaster install (on Ubuntu
Maverick) to 2.6.3-0ubuntu1~lucid1 from:

deb http://ppa.launchpad.net/mathiaz/puppet-backports/ubuntu lucid main
deb-src http://ppa.launchpad.net/mathiaz/puppet-backports/ubuntu lucid main

And now things work sanely.  Still using 2.6.1 from the official
stable repos for clients, seems to work fine.
