Things built for our own house that turned out to be worth writing down. Every guide here was run end to end on real hardware — the commands are the ones that worked, and the dead ends are documented too, because those are usually the part that costs you an evening.
Our products are built on the same ground these projects cover — network storage, Linux boxes that have to survive reboots, and hardware that behaves differently from the documentation. Publishing the working versions seemed more useful than keeping them in a private notebook.
