There are two intended use case for stages and I was hoping we can
split them up into:
1. stages for bootstrap that will halt processing of dependent stages.
2. stages for relationship organization that will not halt processing
of subsequent stages.
stage { 'bootstrap':
ensure => enforcement,
before => Stage['pre'],
}
stage { 'pre':
ensure => enforcement,
before => Stage['main']
}
stage { 'main':
ensure => relationship,
before => Stage['post']
}
stage { 'post':
}
Stages that are enforcement must have all resource completed, stages
that are purely relationship do not block subsequent stages, but
resource dependency still apply within the stage. Would something like
this make sense?
