It's a Sisyphusian Task to to keep things bang up to date.
I hope the number of bugs in Linux asymptotically
approaches zero over a long stretch. But the curve is
ragged – things change for the worse. We hate wondering
about that, so we freeze the installation when it “works”.

We choose a version to use for a long stretch, and we apply
significant patches with puppet, mostly related to security, new
functions or serious bugs that affect us.
Eventually, pressure builds up and we have to choose a new
version to base things on. Then we start again with the freeze.
