> framework properties have several drawbacks (as discussed in SLING-4649)
> * framework properties have to be set before framework start
> * framework properties can not be changed at runtime
> * framework properties can be shared by multiple components _but_ are used as a last resort here only
> * component configurations otherwise can be created and changed at runtime
> * component configurations serve as documentation also
> for components falling back to {{repository.home}} (found by [~rombert]) additionally configurations may be required:
> {noformat}
> oak-blob/src/main/java/org/apache/jackrabbit/oak/spi/blob/osgi/FileBlobStoreService.java:    private static final String PROP_HOME = "repository.home";
> oak-core/src/main/java/org/apache/jackrabbit/oak/plugins/blob/datastore/AbstractDataStoreService.java:    private static final String PROP_HOME = "repository.home";
> oak-core/src/main/java/org/apache/jackrabbit/oak/plugins/segment/SegmentNodeStoreService.java:    public static final String DIRECTORY = "repository.home";
> oak-lucene/src/main/java/org/apache/jackrabbit/oak/plugins/index/lucene/LuceneIndexProviderService.java:    public static final String REPOSITORY_HOME = "repository.home";
> {noformat}
> Not setting {{repository.home}} points us quickly to missing component configurations.
