Hi Carsten, To summarize.
1. Need to clear the start level 1 and keep only logging related bundles and framework fragments at that level. Move all other bundles to Start Level 2 2. For upgraded system we implement a new Bootstrap command say ChangeStartLevelCommand. This would change the start level of bundle from a to b. This would then be used to implement #1 3. For new system the list.xml needs to be updated I would be trying out #2 and come back to the list on how it works in practice. It might take some time given some other work in progress Chetan Mehrotra On Mon, Feb 17, 2014 at 5:37 PM, Carsten Ziegeler <cziege...@apache.org> wrote: > Can someone please summarize what exactly is proposed, especially for > SLING-3388 ? > > Thanks > Carsten > > > 2014-02-12 11:14 GMT+01:00 Felix Meschberger <fmesc...@adobe.com>: > >> >> Am 12.02.2014 um 11:01 schrieb Chetan Mehrotra <chetan.mehro...@gmail.com >> >: >> >> > For now I think we can keep the implementation simple.
