I have a user who was attempting to upgrade his machine this weekend from FC4 to FC5 (both x86_64). However it seems that the Fedora Core 5 installer is not detecting the previous Fedora Core 4 installation on his RAID-1 partitions. The installer jumps right from asking for the localization language to the disk partitioning screen. Is anyone else seeing this problem? Any suggestions on how to debug why FC5 isn't detecting the FC4 installation on the md partitions? Jack
