operations/puppet/modules/scap/manifests/init.pp defines `class scap` which will define the /usr/bin/scap file resource if $is_master is false.
operations/puppet/modules/scap/manifests/master.pp defines `class scap::master` which unconditionally defines the /usr/bin/scap file resource.Backtracking of the issue:
* operations/puppet/modules/scap/manifests/init.pp defines `class scap` which will define the `/usr/bin/scap` file resource if `$is_master` is `false`.
* operations/puppet/modules/scap/manifests/master.pp defines `class scap::master` which unconditionally defines the `/usr/bin/scap` file resource.
* operations/puppet/modules/profile/manifests/mediawiki/scap_client.pp defines `class profile::mediawiki::scap_client` which has parameter `$is_master=lookup('profile::mediawiki::scap_client::is_master')`.
* the instance `deploy-1004.devtools.eqiad1.wikimedia.cloud` has role `role::deployment_server`.
Grepping through operations/puppet for `profile::mediawiki::scap_client::is_master`:
```
./modules/profile/manifests/mediawiki/scap_client.pp:8: Boolean $is_master = lookup('profile::mediawiki::scap_client::is_master')
./hieradata/cloud/eqiad1/deployment-prep/hosts/deployment-deploy03.yaml:1:profile::mediawiki::scap_client::is_master: true
./hieradata/cloud.yaml:335:profile::mediawiki::scap_client::is_master: false
./hieradata/role/common/deployment_server/kubernetes.yaml:128:profile::mediawiki::scap_client::is_master: true
./hieradata/common/profile/mediawiki/scap_client.yaml:1:profile::mediawiki::scap_client::is_master: false
```
When it comes down to it, `profile::mediawiki::scap_client::is_master` should be `true` for any node that uses the `role::deployment_server` class.
Is there a way to change `$is_master=lookup('profile::mediawiki::scap_client::is_master')` into something that finds out if class `role::deployment_server` has been used?
