setting ServerName with Augeas

Question

I am trying to use a Augeas resource to set the ServerName in my httpd.conf like so ...

# configure Apache HTTP server
augeas { 'ServerName':
    context => '/files/etc/httpd/conf/httpd.conf',
    changes => "set ServerName ${controller_name}",
} ->

... but I get this error:

[Debug: Augeas[ServerName](provider=augeas): Opening augeas with root /, lens path , flags 32^[[0m
[Debug: Augeas[ServerName](provider=augeas): Augeas version 1.2.0 is installed^[[0m

[Debug: Augeas[ServerName](provider=augeas): Closed the augeas connection^[[0m
[Error: /Stage[main]/Wrapcontroller/Augeas[ServerName]: Could not evaluate: Saving failed, see debug^[[0m

What am I doing wrong here?

Directives in the Httpd.lns lens are not node labels. Instead, the tree should look like this:

/directive = "ServerName"
/directive/arg = "${controller_name}"

The way to achieve that with Puppet is:

augeas { 'ServerName':
    context => '/files/etc/httpd/conf/httpd.conf',
    changes => [
      'set directive[.="ServerName"] "ServerName"',
      "set directive[.="ServerName"]/arg '${controller_name}'",
    ],
}
