Incremental bundle resolution approach may lead to unresolvable user bundles

When starting up the framework we resolve bundles in stages:

#1 auto install bundles
#2 deployed bundles

within the set of auto install bundles we incrementally run through the start levels
within a start level we iterate over the bundles in the order in which they are defined.

A possible fix would be to first compute the set of bundles that are included (and below) the startlevel that we ramp up to. The resolver would be asked to resolve the complete set.
