Puppet users - Feb 2011 - failing with fail() without failing everything

We would like to have a default node applied to systems, but also
trigger a failure so that we notice the system in puppet-dashboard.

At the moment we''re doing...

node default {
   include system_defaults
   fail("$hostname doesn''t have a node to apply to it")
}

Unfortunately this seems to fail before the system_defaults class can
be applied to the node (which we want applied every time).   And err()
doesn''t propagate up to the dashboard.

Is there any way to accomplish what I want?

Fail function fails the catalog, and without a catalog the client does
not have anything to apply. This is intended as a big red stop button.
You can use bad exec to generate a message and still provide the
resources in system_defaults class which flags this in dashboard (but
I thought this gets applied to ENC nodes anyhow).

exec { "/bin/echo ''not defined''; exit 1": }

This feels like a kludge, and perhaps the following process is better.

Write a function on the puppetmaster that appends a file on the master
about undefined nodes.
Create a notify resource that''s tagged=alertme, and use tagmail
function to email an alert as necessary.

Not sure if anyone else have a more elegant solution.

Thanks,

Nan
