Hello,
Related to recent space saving discussions, I came across PLD's rpm-build-macros package recently, and found that they hardlink identical *.pyc and *.pyo.

The PLD implementation looks like this:

The use of "cmp" would require diffutils installed. Or the above could be converted to use hardlink instead (which would have to be made sure to be around) or maybe sha1sum (in coreutils, pretty much always around in buildroots).
I suppose something like the above could be easily added to redhat-rpm-config or rpm, eg. embedded in brp-python-bytecompile or run after it in %__os_install_post.
Jeremy pinged me about resurrecting this thread, so here goes, the original threads starts at http://www.redhat.com/archives/fedora-packaging/2007-April/msg00003.html for those who missed it.
Anyway, attached is a patch against rpm.org hg for discussion - seems somewhat clumsy to use sha1sum for this but I guess it could be acceptable. Tested on just a few python packages on F-7. Better implementations certainly exist, and are welcome :)
