I'm a Linux enthusiast all the way -- servers, desktops, laptop, android
phone, ddwrt routers, etc.  I suffer to run Windows for some work
applications, but only in a VM.

You need an mdadm.conf file that calls out your arrays by name and uuid.
 Your distro probably put a template in either /etc/ or /etc/mdadm/.
You can append your current running setup with:

mdadm -Es >>/etc/mdadm/mdadm.conf

Then trim the ARRAY lines to just:

ARRAY /dev/md1 UUID=......

Then use 'update-initramfs' or whatever ubuntu is using in 15.10 to
install that into your early boot environment.

Don't forget to fix your timeout mismatch problem.
