Fun and Games and Xenial

I have just finished upgrading my main workstation at home (‘hactar’) from Ubuntu 15.10 ‘Wily’ to Ubuntu 16.04 ‘Xenial’ which, after 3 days of trying, turned out to be one of the most involved upgrades I have ever undertaken. At the end of the day this was because of a bug1 in the LVM2 package on Xenial, and was a bit challenging to fix without just nuking the system and starting again.
