Thanks to all contributors, big time to you Mark, great explanation. My box
works very well, but I am my worst enemy. trying to upgrade from 12.04 to
14.04 has been borking things lately. I am mostly a watch and delete kinda
guy, so I probably wont go through the process 5x, but still great to know.
>From what I see in process things I've changed for Myth don't translate
well across the upgrade, so I guess I'll try a slow clean build, since I
have a drive I can play with.
Daryl
