I did upgrade from F15 to F16 last week (well prior to F16 alpha) with:
# yum --releasever=16 --disableplugin=presto distro-sync --nogpgcheck

Since then I have been doing daily updates with yumex on fedora and
updates-testing repos (as shown above).

Then F16 alpha was announced on Tuesday.
I tried this entry today, on Wednesday, even right now, with those downgrade
results (as shown above):
# yum distro-sync

So, am I still ahead of F16 alpha from the point of view of 'yum distro-sync',
but not from the point of view of yumex daily updates done on fedora and
updates-testing ?
If so:
- should it be so (discovered a problem in 'yum distro-sync') ?
- how can I fix this dichotomy ?
