Christian Schneider commented on KARAF-201:
-------------------------------------------
What I wanted to express is that for each persistence technology you will have
some central resource that can provide a good hook for doing migration tasks.
Karaf features are only used for the first start of karaf. If you restart karaf
then there is only the ordinary bundle startup.
So I think it would not be a good practice to use the feature service at all
for migration scripts. Instead hook into the resources that channel access to
your persistence layer and make sure the migration is finished before the
resource is made available to other bundles.

> {code}
> <script trigger="post">
> // do anything using gogo commands
