[Bug 1482268] [NEW] 15.04 Installer crashes, can't handle mdadm imsm raid1

[John Center]

Public bug reported:

Using the desktop installer, had to manually purge dmraid & install
mdadm with the grub-efi support.  This always fails on the bootloader.
Please fix this, we don't need dmraid for IMSM, only mdadm!
