That's a details of how Linux is managed.

Sure, you can compile and run Python on both versions of Linux, but what if your application uses features that are only present in Linux 3.0 and later ? BTW: The new attribute should contain the complete version number, not just the major version. `uname -r` would provide a good start. ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue12326> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
