Description of problem:
When I unselect "System clock uses UTC" checkbox, hit Forward and then Back, the checkbox is again checked. See attached video.
Version-Release number of selected component (if applicable):
Fixed for rawhide with commit 1fc2308662c4391728eb6cde6ead31bafd6300f7
Ales reports that the call to hasWindows is happening too early, before storage is initialized so this needs a different solution. See https://www.redhat.com/archives/anaconda-devel-list/2010-June/msg00158.html
I cannot reproduce this on current rawhide after reverting the commit. Closing it for now.
