| I'm using puppet 3 with roles (mostly), profiles, and hiera. In one module | |
| (profiles::collectd) I use hiera_array to get the values for pdxcat/collectd's | |
| module's tcpconns_localports variable. When I define all of the values I want | |
| in hiera, everything is fine. However, I would like to also define values in a | |
| profile's class rather than having to define it in every role's yaml file that | |
| includes said profile. I haven't been able to get that to work yet. |
