Subject Re: [DISCUSS] Apache Karaf 4.3.x and resource repositories
Date Fri, 23 Nov 2018 09:45:16 GMT
I do not really understand what this approach does different to features.
Can you elaborate a bit more?

I think it would be great to go more into the direction of repositories and
features that do not have to list all bundles but only the required bundles
to let the resolver find the rest.
As far as I understand this does not require a completely new concept. It
can be done based on the current features.
