DietPi VS AdGuardHome

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.

Also AdGuardhome will use optimistic caching, which is great.

They already have many other commercials products and I guess also the default filter rules are very good because of their experience in the domain.

But I think you can use it completely without the AdGuard servers and use other filter list sources.

How it compares to let's say AdGuard Home? Seems similar https://github.com/AdguardTeam/AdGuardHome

I'm using adguardhome v0.107.42 openwrt snapshot on linksys wrt1900ac v2, but when using DoH it won't resolve upstream DNS, but DoT is works perfectly OK, I've already set allow_unencrypted_doh to true in config .yaml file as per instruction here

AdGuard Home?

Regarding open source, AdGuard DNS actually is:
