Interesting viewpoint (from my Windows developer/user POV :-))
>From my point of view, as a Windows developer, I want to use "system
packages" (bdist_wininst installers) because then I get the benefits
of having a listing of what I have installed, being able to quickly,
easily and cleanly install and uninstall packages to "try them out"
etc. I have the same environment for my one-off scripts as for my
development environment, which again I feel is good as I'm using a
consistent, familiar, toolset.
As a user, I want my applications packaged with py2exe, and
independent of the "system Python" - which for me is the development
environment, and therefore not stable enough to rely on for apps! And
as a developer, py2exe cleanly picks out those bits of my development
environment which are needed in the delivered application, so I don't
have to worry about installing "too much" before I package my
This probably reflects the fact that per-user, or any other sort of
private, installations of Python, are the exception rather than the
norm on Windows, whereas on Unix, building a custom Python to do your
development with (either from scratch, or with things like virtualenv)
is easy and sensible.
I guess the more we see how "the other half" lives (without the
flamewars :-)), the better we'll be able to compromise or provide
options to help everyone.
(Skipped the comments on system packaging, as you've confirmed what I
thought, which is that it's very much a Unix phenomenon, and I'm not
qualified to have an opinion...)
