/dev/mapper and Anaconda install failures (FC6 x86_64)

[Sean Bruno]

I've been wrestling with anaconda this evening on my x86_64 machine.  It
seems that anaconda (or some other piece of the installer) is
forcing /dev/mapper to be created even when I have no RAID devices
enabled.

I have cleared the 'fake' raid stuff off of my disks from rescue
mode(dmraid -E), but with 2 disks installed the installer insists on
trying to configure /dev/mapper/mpath0.

I see each disk individually if I only have one SATA drive connected at
a time.  Which seems odd as heck to me, but I can install FC6 and at
least send you folks this email this way.

Is there a 'nodmraid' option to the installer that I can pass to allow
me to see /dev/sda & /dev/sdb instead of the dmraid stuff?  What's even
stranger is that there appears to be a way to disable dmraid from the
GUI screen when you choose to 'remove all partitions', but the option is
greyed out?!?

Any guidance would be appreciated.
