I had been largely ignoring all the Karaf traffic here. With this, I bothered to actually read the summary and bits of the user guide. I have to say, it sounds pretty cool. At first, it just seemed like a default set of bundles for a felix install, but the more I look, the more goodies I find in there -- OS services, maven support, SSH.
So, should I use it instead of the vanilla Felix we start with? Would you only recommend using Karaf for new projects, or would it be worth it to upgrade an existing app to use it as a base? Thanks, Pat.
