(Not so) Random fortune:
[...] I realised that I didn’t trust the build quality of the [Ubuntu]
LTS releases as much as I trusted the build quality of Debian stable
releases. Thinking about it further, I was having a hard time convincing
myself to run an Ubuntu server. The reason being the way packages are
tested in the Debian repositories. [...] Debian stable is the operating
system that is high production quality.
