BEWARE="
I don't mind breaking my own stuff. 

Here I'm just bulldozing everything I don't want when I'm being lazy and hand crafting artisinal and bespoke installations. 

I'm sure it's a bit unnecessary and reckless. So, no guarantee this won't bork your system or give you trouble with future updates.

Ubuntu gets more difficult to disinfect every release. 

I should give up and stick to Debian sid.
