raspiblitz VS DietPi

All you need to do is to flash the image onto your SD card after you’ve verified its keys and migrate your data from Umbrel after you’ve made a backup.

Learn about the Lightning network and look into setting up a node. https://github.com/rootzoll/raspiblitz

I’m checking out Specter Desktop in my Raspiblitz Lightning node for BTC. The node runs Core as well, but the UI is much nicer in Specter, which is for Multi Sig transactions using any hardware wallet. Doesn’t help with any other coin, though. First Pi project ever, and it’s for science… BTC isn’t my favorite crypto, but it deserves respect. I need to see for myself the scaling possibilities of Lightning first hand. You earn small fees for routing so it should at least break even on power. https://github.com/rootzoll/raspiblitz

DietPi is a lightweight Debian based Linux distribution for SBCs and server systems, with the option to install desktop environments, too. It ships as minimal image but allows to install complete and ready-to-use software stacks with a set of console based shell dialogs and scripts.

The source code is hosted on GitHub: https://github.com/MichaIng/DietPi

That's a good point, but the array of devices supported by the DietPi team is extensive: https://dietpi.com/

Before someone starts the usual yadda yadda about the RPi biger community, the OS not having long time support etc. I would repeat one more time: do not rely on board vendor supplied images; this is valid for pretty much all boards. Just go to Armbian or DietPi pages and you'll almost certainly find one or more images that work on your board and forums to discuss about them with very knowledgeable people.

Those projects are well worth a contribution, as they don't have a giant like Broadcom behind them.

> bananapi do a lot of boards but their software story has been a bit poor

This is quite common with other board manufacturers too. I'd rather suggest to ignore completely their cobbled together distros, often also tainted by proprietary modifications, that become unmaintained in a few years, and see if they're among the many supported by Armbian or DietPi.

RPi OS = diet pi https://dietpi.com/ - initial config via text file - SDcard burning out partially mitigated as writes log files to ram then flushes to SDcard reducing write cycles

You could also try very minimalistic distros like TwisterUI or DietPi which are most known for their use in the RasprebbyPi / SBC computers but which also have editions for desktop / laptop.
