In recent weeks, activity on the usually dormant fedora-ppc mailing list has indicated that we may very well see a new PowerPC version of the Fedora Linux distribution in the Fedora 16 timeframe. (The current version of Fedora is 14, with version 15 due in two weeks.) Actually, the version 15 packages are all ready to go, but there is a serious installer issue that won’t be solved in time to meet that release. However, using yum to do a live upgrade may be possible.
The developers are also changing their policy about using 32-bit userland on 64-bit processors, which is long believed to enhance performance. Apparently, Red Hat Enterprise Linux 6 changed to using 64-bit userland on that hardware, and this is reason enough for Fedora to make the same change.
