The reason we install to the mdX device is so that if your disk dies, the bootloader install is mirrored[1] to both disks. So while it is technically possible to install to the mbr of the first disk, doing so loses the redundancy of the RAID install. Jeremy [1] Although this functionality has wavered a bit between working and not since we switched to grub long long ago. It should be working these days though afaik _______________________________________________ Anaconda-devel-list mailing list Anaconda-devel-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/anaconda-devel-list
