haveged::package

Manage the haveged package

Parameters

The following parameters are available in the haveged::package class:

• package_name
• package_ensure

package_name

Data type: String[1]

The name of the package to manage

Default value: defined('$haveged::package_name') ? { true => getvar('haveged::package_name'), default => 'haveged'

package_ensure

Data type: Simplib::PackageEnsure

haveged::service

Manage the HAVEGEd service

Parameters

The following parameters are available in the haveged::service class:

• service_name
• service_ensure
• service_enable
• force_if_rngd_running

service_name

Data type: String[1]

The name of the service to manage

Default value: defined('$haveged::service_name') ? { true => getvar('haveged::service_name'), default => 'haveged'

service_ensure

Data type: String[1]

Whether the service should be running

Default value: defined('$haveged::_service_ensure') ? { true => getvar('haveged::_service_ensure'), default => 'running'

service_enable

force_if_rngd_running

Data type: Boolean

Will force haveged to start even though RNGD is already running

• While this should not harm your system in most cases, it is also adding an unnecessary process running on the system

Default value: false
