Assuming you're trying to solve the problem I think you're trying to
solve (i.e. to have Apache with the correct process model installed
before any additional modules), it's important to note that reordering
the array doesn't guarantee that. The order in which Puppet applies
resources is non-deterministic unless you have explicit ordering.
You're probably better off solving this problem in a different way; for
example by creating a new data element (e.g.
profiles::webserver::apache::process_model), and then specifying
explicit ordering between the process_model package and the modules
packages.
This also gives you the added advantage that it becomes impossible to
have multiple process models listed for a given node, assuming that you
make the new data element a string rather than an array (since it will
get overridden instead of merged).
If my understanding of your problem is incorrect, perhaps you could
describe the problem you're trying to solve. Relying on the order of
array elements is probably a poor approach in the Puppet model, so there
might be a different way to solve the problem.

Hi,
Given the following structure:
hiera.yaml:

:hierarchy:
- nodes/%{::fqdn}
[...]
- common
:merge_behavior: deeper
common.yaml:
[...]
profiles:
webserver:
apache:
modules:
- auth_kerb
- authnz_ldap
- cgid
- status
host.yaml:
profiles:
webserver:
apache:
modules:
- mpm_event
- php
- ssl
hiera_hash ('profiles')['webserver']['apache']['modules'] returns the
following array:
[auth_kerb, authnz_ldap, cgid, status, mpm_event, headers, proxy,
proxy_http, rewrite, ssl]
mpm_event may also be mpm_prefork and mpm_worker.
How can I ensure that mpm_* is always the first element in the array?
Thank you
