XUbuntu 20.04 install on raid does not install mdadm

[Alan Pettigrew]

I chose to re-install XUbuntu rather than upgrade 18.04 to 20.04.
I loaded the Live DVD and installed mdadm.
The root FS is not on raid.
I ran the install and marked /usr/local as /dev/md0, and /home as /dev/md1.

When I rebooted after the install the system got to the Login prompt, but went no further.
I managed to boot to the root prompt, which has no network started by default.
Having started networking, I installed mdadm, and could then boot into my user.

The install process needs to install mdadm automatically if there are raid disks in the configuration.

I do not know whether this was a problem in earlier releases as I have not done a fresh install since introducing raid. Upgrades seem to work as expected.
