As said before, this series, atleast the second patch, depends on Henning's 
base-apt series.

I am going to rebase my changes on top of Hennings v5 and test it out.

Also, should we have these changes as part of Hennings series? Or should I 
wait for
the series to get in and address these later?

Thanks,
Vijai Kumar K
