-------------------------------

Indeed, that's a better solution. Could this version be released? It would save some hassle to get a snapshot in my production environment.

> I want Preference Service to persist stored preferences and have them survive system restarts. Preference Service stores its stuff in the OSGi frameworks' cache region, which get cleared on restart (by Pax Runner, which is what I use). Trying to get around this was problematic, so I figured it would be nice to be able have the preferences database outside the cache directory. A system property like "felix.prefs.rootdir" could be used to set the location.
> I patched the Preference Service from trunk to get this feature and the changes are minimal, I just added the following lines to the DataFileBackingStoreImpl constructor:
>         String configuredRootDir = System.getProperty("felix.prefs.rootdir");
>         this.rootDirectory = configuredRootDir == null ? context.getDataFile("") : new File(configuredRootDir);
>         this.rootDirectory.mkdirs();
