This is not really Red Hat's fault. I used the installer disk with ATA100 support (see freshmeat) to use the Promise Fasttrak66 raid card in our toy-server. The person who made this disk forgot to enable RAID in the kernel, and as a consequence the installation-script aborted with a Python error when attemting to mount the just-created raid partition. Although I fully realize this is not a Red Hat bug and totally my problem, I think it would be a nice tough if a failure to mount the raid partition would not crash the installer.
Added to feature list.
Could you give us the traceback that occurred?
Not right now. It occured while installing RH7 at a server at work, which is now operational. Once someone sells RH7 in the Netherlands, I'll reproduce it on one of my test-boxes and give the backtrace.
