Mainly a question of style.
You can use the graph feature to see everything :
( except that we do not provides them purely by slack )
I guess a simple task to learn puppet would be to make them usable by
everybody. But I can also do it quite fast, if you need to look to the

This seems quite overkill for simple module, and I am not sure it will
help to reduce so much the complexity on complex module ( such as sympa
or subversion ). While I would agree that we should have some shared
style to help rereading the code, I also think this is one issue that
can trigger some heated arguments. Despite being annoyed every day by
the mix of space and tabs in subversion or buildsystem, I never pushed
for uniformisation there, but maybe that should be done.

It greatly depend on what you mean by "work" :)
I do not see obvious reasons it would break something, and to me, the
question is just to know if too much division will really improve
It is like java. I like the java layering and separation of modules, at
least on paper, it is quite clean. In practice, there is this feeling of
awful complexity due to the separation and heavy use of object
I can understand your frustration of having to read a large corpus of
code/configuration without having this feeling of a clean base ( ie,
different conventions, lack of style, etc ). And we do have some need
for cleaning and consistency for sure.
But on the other hand, having a too rigid structure of things may have
been too constraining for a small team, to start.

The granularity is already achieved at class level, and I think we are
quite good at this point. Too much would maybe be over-engineering at
this point, we only have 7 servers :)
