ubuntu-phone team mailing list archive

We expect that applications that need sophisticated dependency schemes
will include those dependencies in their own packages.  There will be a
base image that everyone can depend on, but beyond that, you'll need to
BYOD (bring your own dependency).

There'll be a difference between packages that are part of core Ubuntu
(the archives) and those that are distributed via the Software Center.
Applications in the archive will continue to have the rich dependencies.

All of this is under the title of "Click Packages" and is being
discussed at vUDS in a few hours:
