looking at the patch this option does not more than:

 +            run(["cp", "-al", settings.cowbuilderpath, self.name])

so it simply copies the chroot from cowbuilders basepath to a new
directory and uses it, instead of unpacking pbuilders base.tgz. That
also explains why cowbuilder doesnt store any aptcache, because its not
even called.

Im not sure if this is .. "cowbuilder integration": its basically an
option to use whatever directory tree as chroot, which is indeed useful
as it saves time and would be nice to have in the archive.  (having to
tar -zxf pbuilers .tgz each time simply sucks, it wastes time).

Maybe cowbuilder can be integrated better, but then im not into python
at all.

bye,
