I just found this on the wiki and it may help out in this problem:
class base_class {
define testvar_file($myvar="bob") {
file { $name:
content => template("john.erb"),
}
}
testvar_file { "/tmp/testvar": }
}
class child_class inherits base_class {
Base_class::Testvar_file["/tmp/testvar"] { myvar => fred }
}
it is at http://reductivelabs.com/trac/puppet/wiki/CommonMisconceptions
under Class Inheritance and Scope.
