The other directory (/usr/lib/...) is one of the default locations in the $LOAD_PATH and so that is why the backends are placed there.
At the moment you can't easily ship hiera backends in puppet modules because of this limitation. What you'll need to do is after you've installed the module add that module's lib directory to the RUBYLIB environment variable so that ruby picks it up when running puppet. > My question is really: why isn't sidb_backend.rb being copied into > /usr/lib/ruby/site_ruby/1.8/hiera/backend by puppet -- and more > fundamentally, why is puppet choosing that path? > > I've been looking for a M to RTF, but the best I've found is: > https://github.com/puppetlabs/hiera/blob/master/README.md, but it doesn't > have a lot of help for writing your own backend > > I don't think there is too much documentation about how to write hiera backends, and the issue that you hit with getting it to load is related to an existing bug that we are working on: https://projects.puppetlabs.com/issues/7316 > Appreciate any help you can provide, > > -Conor > > -- > You received this message because you are subscribed to the Google Groups > "Puppet Developers" group. > To post to this group, send email to [email protected]. > To unsubscribe from this group, send email to > [email protected]. > For more options, visit this group at > http://groups.google.com/group/puppet-dev?hl=en. > -- You received this message because you are subscribed to the Google Groups "Puppet Developers" group.
