Unable to force arch for installing exporter

[defenestration]

Trying to run node_exporter on an RPI 1. There are releases for it here: https://github.com/prometheus/node_exporter/releases (the armv6 in this case). However i seem unable to force the arch for the module using hiera prometheus::node_exporter::arch since in init.pp it seems to force one of the main arches there.

[root@dns-pi ~]# cat /proc/device-tree/model
Raspberry Pi Model B Rev 2

Affected Puppet, Ruby, OS and module versions/distributions

• Puppet: 4.8.2 (from raspbian repositories)
• Ruby: ruby 2.3.3p222
• Distribution: Raspbian GNU/Linux 9.4 (stretch)
• Module version: 6.2

How to reproduce (e.g Puppet code you use)

classes:

• prometheus::node_exporter

prometheus::node_exporter::arch: armv6
prometheus::node_exporter::download_url: https://github.com/prometheus/node_exporter/releases/download/v0.16.0/node_exporter-0.16.0.linux-armv6.tar.gz

What are you seeing

Evaluation Error: Error while evaluating a Function Call, Unsupported kernel architecture: armv6l at /etc/puppetlabs/code/environments/production/modules/prometheus/manifests/init.pp:189:7 on node dns-pi

What behaviour did you expect instead

installation of node_exporter

Output log

Any additional information you'd like to impart

Realize it is a pretty fringe case, sorry bout that. Probably simple to add? but not sure how other services would be affected. I was surprised node_exporter has a few arm releases actually.
