For me, the ease of self-hosting my own source-code hub tipped the balance in favor of Fossil SCM, after I abandoned Subversion. Ironically, the difficulty of self-hosting Git was the raison d'être for why inherently centralized services such as Github/Gitlab/etc were created in the first place, despite all the nice talk about distributed systems. There is no a priori reason why hosting a source code repo should be any different from hosting any random blog page. And Fossil is the proof that it can work.

Anything not enforceable shouldn't be in the contract in the first place. The only purpose of contracts is to enforce earlier promises when people don't agree anymore.

I have a NUC6i5SYK (Skylake) running Ubuntu 16.04 server, and I too had some serious problems initially. Installing to the SSD worked without issues, but then I got machine check panics during most boots. After a lot of troubleshooting I was finally able to make the system stable by adding these parameters to the kernel command line:

  intel_idle.max_cstate=1 i915.enable_rc6=0

After that it has been running without a glitch. I hope it will be as stable as the Mac Mini it replaced. That too had some initial problems however: the first one I bought in 2008 was DOA. Apple replaced it, and the replacement lasted four months before a thunderstorm zapped it. My insurance company replaced that one, and that Mac Mini then ran like a clockwork 24/7 for eight years.
