I still think that a PREFIX file, that contains *all* prefixes which are configurable during installation right now, should make it to PEP 376 and to Python 2.7/3.2 . These prefixes could be kept unexpanded in the RECORD file and it would therefore only be necessary to change them within the PREFIX file if one wants to relocate an installation. (Is this really a common use case?) The PEP lists $PREFIX and $EXEC_PREFIX, but the set of prefixes that are configurable during installation comprises: Prefix Default value Command line option ----------------------------------------------------------- PREFIX sys.prefix --install-purelib EXEC_PREFIX sys.exec_prefix --install-platlib SCRIPTS_PREFIX $PREFIX/bin --install-scripts DATA_PREFIX $PREFIX/share --install-data I think that it'll help Linux distribution developers *and* Python developers a lot if these prefixes where available during runtime or could be obtained by parsing the PREFIX file. This would mean the end of __file__ magic to find data files and Python packagers could adapt their tools to copy, for example, a configuration files from $DATA_PREFIX/foo.cfg to a location that complies with the FHS (i.e. /etc/foo.cfg). > It seems feasible to me in both cases.
