  You've misunderstood.  The setup.ini files *are* getting merged correctly, and
as a result you have the option of installing any of the packages that you have
stored in any of the download directories.  However, setup.ini only stores the
list of available packages; it does not carry the particular selection that you
have installed in a particular machine.

  Yes.  The information about which packages you actually have installed lives
in /etc/setup/installed.db.  If you copy over the installed.db from the old
machine to the new one (in the correct place where it's going to live in the
eventual new cygwin installation, i.e. C:\cygwin\etc\setup\installed.db if
you're going to install to C:\cygwin), run setup.exe, tell it to install from
the local package dir that you've already copied across and on the chooser page
click 'reinstall' at the top level of the package tree view, it should then
install the same set of packages.

    cheers,
