Well, I think that the current plan is to switch Anaconda to Python 3 once all dependencies can run with Python 3, not making it 2 & 3 compatible, due to all the additional development & testing overhead. On the other hand I think Blivet & Pykickstart will use the 2 & 3 compatibility route, as they are used on various (older) systems and not just on Fedora. > > [1] No formal commitment on timeframe, it was a verbal agreement with a major consumer of the OS, but if I had to handwave this, "long time" = "RHEL major version". > > _______________________________________________ > Anaconda-devel-list mailing list > Anaconda-devel-list@xxxxxxxxxx > https://www.redhat.com/mailman/listinfo/anaconda-devel-list _______________________________________________ Anaconda-devel-list mailing list Anaconda-devel-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/anaconda-devel-list
