No option to turn off overwriting of the file if it is later changed

[threepistons]

Given

• Ubuntu 18.04
• Puppet agent 6.0.2
• Puppet server 5.5.3
• nsswitch module 2.1.0
• Hiera as follows:

nsswitch::passwd:
  - sss
  - files
nsswitch::group:
  - sss
  - files
nsswitch::shadow:
  - sss
  - files
nsswitch::sudoers: files
nsswitch::gshadow: files
nsswitch::networks: files
nsswitch::netgroup: sss
nsswitch::protocols:
  - db
  - files
nsswitch::services:
  - db
  - files
nsswitch::ethers:
  - db
  - files
nsswitch::rpc:
  - db
  - files
nsswitch::hosts:
  - files
  - 'mdns4_minimal [NOTFOUND=return]'
  - dns

• A Puppet-managed workstation where the nsswitch.conf file has been modified after deployment.

When I

Run puppet agent -t as root on the workstation.

In order to

Restore the nsswitch.conf file to how I defined it in Hiera.

I get

The file does not change.

I expected

The file to be overwritten with the content specified in Hiera.

I suspect this is because

The file resource in init.pp doesn't specify "replace => yes".

This is actually because of an error in my manifest: the module is configured but never actually called. I offer my apologies.

Whilst trying to figure out what was going on, I've written in the ability to turn off overwriting. It's in my fork if you think it might be useful. I've edited the issue title to reflect the new feature.
