There is also a legacy function still in the config.pp:

  errors:
    Evaluation Error: Unknown function: 'has_key'.
      file: modules/prometheus/manifests/config.pp
      line: 262
      column: 9
      factsets: RHEL8

@hashworks do you want to rebase this on top of #668 and address the issue raised by @marszip? This should fix CI :-)

[smortex]

The validate_* functions where made useless with datatypes introduced with Puppet 4. $foo =~ Boolean can be used when the datatype cannot be enforced directly at class parameters.

The dependency on postfix should be fixed by this PR when a new release include it:
voxpupuli/puppet-postfix#357

[bastelfreak]

also contains #670

[bastelfreak]

released voxpupuli/puppet-postfix#359

[bastelfreak]

needs a new release for https://forge.puppet.com/modules/saz/sudo : saz/puppet-sudo#294
