A few months ago in a random post-PyConAU fit of hackery, I got disk-image-create in TripleO's diskimage-builder project running on openSUSE 12.3, i.e. you can now run disk-image-create on an openSUSE system, and have it create, say, an Ubuntu system image. Time to take the next step, and make it capable of building openSUSE images ;-)

Project Description

At my home we have solar PV hooked up to Victron inverter/chargers and a Redflow ZCell battery for energy storage. The setup is described in detail on my blog. By their nature, ZCell flow batteries needs to undergo a maintenance cycle at least every three days, where they are discharged completely for a few hours. Having only one battery, this means we can't use the "minimum state of charge" feature of the Victron kit to always keep some charge in the battery in case of outages, because doing so conflicts with the ZCell maintenance cycles. This isn't a problem if you have more than one ZCell, because the maintenance cycles interleave in that case, but so far we only have one of these things. If I want to keep charge in the battery for emergency purposes on non-maintenance days, I can do that by configuring scheduled charge settings manually on the Victron Cerbo GX console, but then I have to remember to turn those things back off (or otherwise adjust the settings) for the next maintenance day. For this hack week, I'm going to see if I can automate that piece somehow.

I have three hundred and eighty four openSUSE 12.1 DVDs. Given 12.1 went end of life almost ten years ago, it seems likely these DVDs are useless. Rather than toss them out I've decided to try to turn them into some form of art.
