We deliberately removed mdadm from the default installation several releases ago; it makes the boot process slower and more complex, and for most people without RAID arrays it's just a waste of disk space. Of course, it's installed if you have a RAID array available during installation. The desktop CD explicitly does not yet support RAID, although it may do in the future.
