Hi
Thanks for the explanation. As this is a topic that needs more
background, and a deeper discussion, I created an etherpad to work on it.

Hello All,
At the meeting on August 25th, we discussed an issue with the
puppet-httpd module and a few solutions. The issue is that the
httpd_mod type does not have a baked-in ordering relationship with the
Service['httpd'] resource. This means that sometimes httpd_mod
resources are instantiated after the service attempts to come up,
meaning the service cannot start.
A few solutions have been proposed:
1) Modify our use of the httpd_mod resource to use 'before'
everywhere. This patch [1] is an example of doing that for
puppet-gerrit, we'd have to perform similar modifications elsewhere in
our code.
2) Modify the httpd module to do this automatically. This patch [2]
changes the type at the ruby layer using puppet internal apis to add
an 'autobefore' on the Service['httpd'] resource.
3) Create an httpd::mod defined type that can do this automatically.
We'd have to then change every invocation of httpd_mod to be
httpd::mod. This patch [3] is the patch to create httpd::mod and this
patch [4] shows what using it would be like. We'd have to apply
changes like [4] everywhere in our infrastructure.
4) Migrate to puppetlabs-apache. This has two forms, one(4a) involving
patching that module to support our usecase and the other(4b) where we
use the existing api.
I have my own opinions about what we should be doing, but this message
is meant to explain the problem and roads available to us, not to
editorialize.
