Very cool to hear about this first hand, thanks for posting it Allan. I was recently at the Ubuntu Developers Summit and Arch Linux's transition was a source of several hallway discussions. It's good to read about your work and successes in blazing that trail. >I really do not want to debate the sanity of pointing /usr/bin/python at >python-3.x here, but it suffices to say that I am of the opinion that if >python-3.x is really the future of python, then /usr/bin/python must >eventually point to a 3.x version.

Ah too bad, no one needs to yell :). It's an interesting discussion topic though and it's something I think other distros should start considering. In Ubuntu 11.04, we'll have Python 3.1 and 3.2, 2.6 and 2.7, with the default (i.e. /usr/bin/python) either at 2.6 (probable) or 2.7 (possible). `python3` currently points to 3.1.2, but we've talked about getting that to 3.2 for this cycle. Ubuntu's next Long Term Support release is scheduled for April 2012. It's an ambitious but worthy goal to see if we can transition to Python 3 as the default Python by then. -Barry
