2 & 3 can be merged using easy-deb with the right template of debian/rules.
even 1 & 1 can be merged using easy-deb to create a package that the debian
developer will manually patch to remove/change egg functionality.
I think setuptools could really help Debian developer as well as Fedora,
Mandriva, Gentoo... by:
1) providing functionality to install files outside of egg dir/zip (for
example one could install code to site-packages and data-files to /usr/share/
or somewhere else)
2) providing a "fakeroot" option to fool setup.py (for example I want
setuptools to install the files in debian/tmp/usr/lib/pythonX.Y/site-packages
and scripts in debian/tmp/usr/bin and everithing must work when it copied
2) providing a paseable output with setup process data like: dependencies
(meet and unmett), files installed, author, license, and so on
All this will let people just "convert" the output of setuptools into an rpm
specfile, debian dir, gentoo ebuild and so on.
All that is needed is just a common metadata format that can be parsed by
tools like easy-deb, easy-rmp easy-ebuild easy-(???).
This way setuptools provides the information to distribution maintainers in a
well documented, api independent way. Distribution maintainers can use this
info to reorganize, repackage, invent new package formats, but without
involving setuptools and python developers.
About the pythonpath and pth files handlind:
if a project A really wants to use project B eggs it can easily require them
without the need for a pth file.
If project C wants to use project B, but project C is not setuptools aware one
could patch project C (just adding require() to it) instead of paching
project B and project A removing egg support from them.
Onother possible solution would be to have:
python-B) depends on python-pypi-A and just provides the pth file (handled
like easy-deb does)
python-pypi-B) contains the egg
So project C will depend on python-B, which will install the pth. But if
project B is required just by project A which is setuptools aware the
dependency will be on python-pypi-B: the pth file will not be installed.
