Most distros won't use /opt. We tend to follow the FHS.
/opt makes a lot of sense for the binary pypy you distribute. Just as it
makes sense for the binary junk that Adobe et al. distribute.

Having the same installation layout on all distros would be fantastic.
Practically, that gets non-trivial, though. Debian has the weird
dist-packages layout for cpython, that I copied for pypy, but that
approach hasn't been documented in upstream cpython or adopted by any
other distributions.

I did my best to make you all aware of it, and get some feedback.
I mentioned the PEP3147 support here [0], and a zillion times on IRC.
But I have no problem having that conversation now that people seem to
be aware of it :)

Yup, that's the opinion I felt before. And the approach I'm taking. But
the patch is fairly gnarly due to test-suite changes, so I haven't
forwarded it up to you.
