Specifying templates with non-OS criteria

Chef Infra (archive)
1

The docs regarding template specificity indicate the OS is the only
criteria that can be used for dynamically choosing a template:

The pattern for file specificity is as follows:

  1. host-node[:fqdn]
  2. node[:platform]-node[:platform_version]
  3. node[:platform]-version_components: The version string is split on
    decimals and searched from greatest specificity to least; for example, if
    the location from the last rule was centos-5.7.1, then centos-5.7 and
    centos-5 would also be searched.
  4. node[:platform]
  5. default

Can I use other criteria? I would like to choose a template based on metal
vs VM.

Thanks a lot,
Guy

If that's an attribute you have available you can base it on that:

template "/etc/some/template" do
source "#{node['server_type']}/template.erb"
< other stuff >
end

Then store the templates in the cookbook templates folder under:

./templates/default/metal/
./templates/default/vm/
