We have a parted update to fix a new blocker:
http://bugzilla.redhat.com/show_bug.cgi?id=747497
https://admin.fedoraproject.org/updates/parted-3.0-4.fc16
I've built a boot.iso with the updated parted for testing, it's
available here:
http://adamwill.fedorapeople.org/20111027_preRC1.x64.boot.iso
please give it a shot and upkarma the parted update if it looks okay.
You can try to test the fix by installing into free space alongside some
existing partitions, and checking the installation doesn't change the
flags on the existing partitions.
thanks!
