Yes. Every line in your config file (that is not a text line like a
comment) will be parsed as one record. During prefetching puppet tries
to match the resources the user has defined in his manifest with the
records of your target file(s).
It works like this
Puppet iterates over every record. If puppet has a resource with a name
that matches the current record's name then puppet creates a provider instance
and assignes the provider to this resource.
So in short
* each resource has zero or one prefetched provider
* one provider corresponds to one specific record in your file
Have a look at provider/parsedfile.rb method
match_providers_with_resources
You may be able to define a custom prefetch_hook method in your
provider where you merge your different records into one. But I
currently don't know how puppet behaves when it has to rewrite the file
after possible changes.
Untested prefetch hook:
def prefetch_hook(records)
merged_records = {} # hash with the record's name as key
records.each do |record|
if name = record[:name]
merged_record[name] ||= {}
merged_record[name].merge!(record)
end
end
merged_records.values
end
You may get additional suggestions if you look at the cron provider.
But in general I'm afraid that the parsedfile provider is not really
good when information spanning over multiple lines.
