This was observed on ia64 with fedora core development. In our mirror, the kernel was at kernel-2.6.12-1.1485_FC5.ia64.rpm and anaconda was at anaconda-10.3.0.7-1.ia64.rpm. I had a previous install of Fedora Core development on the machine. I wished to wipe it out and start over again with a new one. I even marked the FC related filesystems for "re-format" in disk druid. Other non-Fedora/Redhat operating systems were present on the machine. I was never given the menu where you can select "workstation, server, custom, etc" like I was before. Instead, it just started installing stuff even though it formatted the filesystems fresh. When I booted in to a different OS on the machine and re-created the filesystems that previously held FC Development, rebooted, and tried the install again... Then I was given the chioce to install workstaiton, server, custom, etc. Therefore, it appears that if the FC installer sees that there is an FC already on the disk, it seems to skip allowing you to select what type of system you'd like. Please be advised that this could be related to bug 166088
Yes, this is most likely related. We currently have the upgrade and "pick your installation type" disabled.
Update screen is back and should be working.
