No way to define different keys for "auto" in different hiera sources

[sdelafond]

I'd like to have a merge behavior by default, using the following hierarchy:

common.yaml

unattended_upgrades::auto:
  remove: false
  reboot: true

nodes/foo.yaml

unattended_upgrades::auto:
  reboot: false

Unfortunately, hiera_hash() isn't used for the auto parameter, so we end with the default priority lookup instead, and "remove:false" isn't used on node foo.

since this is a puppet """""""feature"""""", the only way to fix that is either repeat yourself, or wrap this class into a profile.

:( closing this, as "can't fix" ):

It believe it can be fixed: this behavior is just the default for automatic parameter lookup. How about something along those lines ? https://www.sidorenko.io/blog/2014/07/05/puppet-hiera-hash-merge-and-automatic-parameter-lookup/

Does this not sound like an acceptable solution ?

That would explicitly require us to add all the hiera_hash() calls in a bunch of places and not everyone might even be needing it, meaning more things to check and more special cases to deal with.

What you want can be achieved by changing Hiera's Hash merge behaviour: http://docs.puppetlabs.com/hiera/3.0/configuring.html#mergebehavior. You'll want to set :merge_behaviour: deeper and gem install deep_merge on your Puppet masters. If you're running Puppet 4 AIO you can /opt/puppetlabs/puppet/bin/gem install instead.
