Subject Re: [DISCUSS] Align Karaf deployer and felix fileinstall
Date Mon, 15 Jun 2009 14:31:07 GMT
I think this sounds reasonable as long as it keeps the basic simple 
functionality in tact by default and the implementation remains simple 
overall, since that was the original goal, as mentioned by Sahoo and 

It doesn't sound like the added features add too much complexity and 
could also be made optional where appropriate. So, that sounds good.

The original idea for FELIX-922 (supporting different types of files) 
was to create something really lightweight, such as a simple handler 
service interface which the core could retrieve from the service 
registry and other bundles could implement. It sounds like this is what 
has been done, so that seems good too.

Also as mentioned, merging might be more difficult, since the code bases 
have changed, but merging features sounds possible.

I had also wondered about supporting start levels. My original thought 
there was to create numbered subdirectories that correspond to the start 
level for the contained bundles; however, that might be problematic with 
exploded bundle support...something to think about.
