I was thinking about similar lines. So far, I didn't have much luck with
the features: either installs or uninstalls didn't work properly or I
was too lazy to write my own features. And I want more control over
which bundles are installed. So currently, I don't use features at all
although I'm a happy Karaf user.
If I had some free time, I'd write a bundle that gets a directory which
has subdirectories with the bundle level as their name. It would set up
all bundles with the framework using the right start level. That sounds
just a bit like FileInstall but I would not include a directory poller.
Example:
-- deploy
+-- 10
+-- spring-core-2.5.6.jar
+-- spring-beans-2.5.6.jar etc.
+-- 20
+-- activemq-core-5.3.0.jar
+-- activemq-pool-5.3.0.jar etc.
Well, in a perfect OSGi world, bundle levels shouldn't be necessary but
reality shows problems with Spring and other bundles.
