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,

With the current implementation it is difficult to append a
postprocess function which requires a chroot environment.
For example, to add a postprocess function which runs apt-get to
download all source of packages installed in the target.

rootfs_postprocess_finalize is not actually an optional feature
but instead a necessary cleanup function for image class.
So, move the implementation to image class and make it as a task.
