hard drives grow to be almost too large for a "normal" system drive--is to
just create a few 20-30GB partitions for your root partitions for multiple
installs/versions, then install your Mythbuntu on one of them and leave the
other(s) blank. Then, when time for an upgrade, install a new Mythbuntu to
a different partition***, and boot into that system. If you're not happy,
boot back into the old partition to record that important show during prime
time and to relax and watch some TV, then boot back to the new partition to
work on it some more when you get some free time. This gives you the same
ability to easily switch back and forth between the two installs that you
get with a VM. The only thing you don't get is the ability to run both at
the same time.

probably get help on how to do this from Mythbuntu/Ubuntu users.

12.04 + mythbuntu-repos. You will only need to upgrade every 2 years and
you will get the latest versions of mythtv
