Hi Edward, With puppet 3.7, all facts are "stringified" by default, meaning hashes are flattened to strings. If you've got facter 2.0 or greater, you can change this behavior do you can access hash keys individually.
https://docs.puppet.com/puppet/3.7/reference/lang_facts_and_builtin_vars.html#data-types Be sure to also read the next section below the one I linked for some gotchas. Also, if you want to access $facts as a hash, make sure to set he option notes here: https://docs.puppet.com/puppet/3.7/reference/lang_facts_and_builtin_vars.html#the-factsfactname-hash -- Peter (from phone) > On Jun 17, 2016, at 8:42 AM, Edward Ned Harvey (puppet) > <[email protected]> wrote: > > Running puppet 3.7.4 > > I am new to puppet, and learning the syntax.
