Honestly, I'm not sure we want to use this in Fedora. Is anyone

reproducible builds, to make a better argument for this?
I believe rpmbuild (et al) all set SOURCE_DATE_EPOCH in the
environment, so Fedora's likely to get the new CHECKED_HASH behaviour
by default:
https://docs.python.org/dev/library/py_compile.html#py_compile.compile
Given that SELinux typically won't allow user applications to rewrite
the bytecode anyway, we may want to specify the use of UNCHECKED_HASH
at build time instead - with that setting, Python will ignore source
file changes entirely, and trust that RPM will keep the source and pyc
files consistent.
Cheers,
Nick.
