I'm running an experiment with an arbitrarily large system partition on
a (virtual) Tails USB stick. It has all incremental upgrates applied on top of
a Tails 2.0 installation. The goal is to identify shortcomings that come with
applying many incremental upgrades. It doesn't boot anymore unless I set
loop.max_loop=N, with N large enough, on the kernel command-line. Let's make
this work out of the box, which might also help with various other experiments
we could want to do wrt. endless upgrades.
