[rhelv6-beta-list] EFI fstab error during upgrade to snapshot 7

[Adam]

    When I attempt to upgrade my snapshot 6 install to snapshot 7, the 
installer fails right as I select my drive as the "Install Target 
Device".  The error I see seems to boil down to:

"scanned format (efi) differs from fstab format (vfat)"

This is evidently referring to my /boot/efi partition being logged in 
fstab as a vfat partition.  All references I've seen have the /boot/efi 
partition as vfat, so I'm assuming that it should be.  I recall setting 
it up as vfat when I initially installed.

Why is the upgrade process implying that it should be a different type?
