Angel, I'm moving your query to the bug-cfengine list, which is where
the package management code is currently being discussed.
What you are saying below is entirely possible, and I agree with your
suggested fix. But to fix this problem someone would need both
platform familiarity and a test system. It would be a great help if
you were to take on updating the DPKG routines to work better. If
you are not already on the bug-cfengine list, please subscribe and
submit your suggested patches there.
FYI: a lot has changed between 2.1.20 and 2.2.2, however not the DPKG
code. Can you download the latest trunk and give us patches against
that?
