## When writing relation script, remember:
|
|
## - they should be idempotents
|
|
## - they can be launched while the dockers is already up
|
|
## - they are launched from the host
|
|
## - the target of the link is launched first, and get a chance to ``relation-set``
|
|
## - both side of the scripts get to use ``relation-get``.
