Re: On the plus side
"I've tried upgrades of 3 12.04 machines."
That's the one thing I've yet to understand, if a machine's kernel and all its packages are updated to be the same as the new release, shouldn't the system count it as the new release? A sort of "Ship of Theseus" problem, I suppose.
But the mess with trying to label Linux distros by a version number is why I decided to roll my own (well, one of). I don't need any of the thousand and one packages that the various distros think I need (Like that Unity bullshit from a few years ago...)
