When installing Fedora on machine with -large- amount of drives (8-16), I simply use a single sfdisk script to create the same partition table on all drives. When dealing with smaller configurations (3-4 drives), Anaconda is OK. (At least to me)
As for MBR: I assume that like me, you create a small RAID1 for /boot and RAIDX for the rest, hoping the first disk won't die on a DVD-less machine :) In-order to solve it (when I remember to do it :)), I simply dd 446 bytes from the first drive to every other drive.
Just curious: you script the creation of an identical partition table, and then you copy 446 bytes which specifically copies the MBR without the partition table which is in bytes 447-512. Why not just copy the entire 512 bytes to all the disks from the first one?
I guess one reason might be if the disks did not have identical CHS geometry, which can happen for the identically sized disks. I have heard rumors that even a single model drives had been seen with different geometries in different firmware revisions.
