Puppet users - May 2011 - puppet code to find out which is the first active network interface

I have a piece of shell script as below:

ACTIVE_INTERFACE=`/sbin/ifconfig | /bin/gawk '' /^eth/ { print $1 }
''
| /usr/bin/head -1`

How do I translate it to puppet code, for example to assign the result
as a variable to use?

Thanks,
-Haiyan

You want to write a custom fact, for Facter.  Normally you would
distribute that as part of the pluginsync process, so it would be sent
to the client by Puppet automatically, and available before your
catalog was compiled.
