Release level modification in text upgrade test cases

[Petr Schindler]

I propose to change release level of [1] [2] from beta to non-blocking
(leave it blank). There is a thread [3] anaconda-devel list, but nobody
has replied. I hope that someone from anaconda will react on this
proposal. If text upgrade will be supported in f17, there is a bug from
last release [3] which should be fixed.
