Michael Lynch ☛ Installing NixOS on Raspberry Pi 4
I only recently started experimenting with Nix, and there’s a huge amount to learn. One of the first things I tried to do was install NixOS on my Raspberry Pi, but my first several attempts failed. Every NixOS Pi tutorial I could find was either incomplete or out of date.
I present to you my complete and working guide to installing NixOS on a Raspberry Pi 4. I’m a newcomer to NixOS, so this guide is for Nix beginners, but I assume you have basic familiarity with Raspberry Pi and Linux.

Barry Kauler ☛ Guvcview added to Easy Excalibur
The original question was asked on the forum about Droidcam, then the missing Guvcview was reported:
https://forum.puppylinux.com/viewtopic.php?p=157388#p157388
Yes, the Scarthgap-series is highly refined; it has both Droidcam and Guvcview builtin. Guvcview is in the Debian repository, so I have now added it; it will be builtin.

Barry Kauler ☛ Linux kernel 6.12.50 compiled
A week ago, compiled the 6.12.48 kernel, with extra modules required to support wireguard and wg-quick:
Now that we have embraced overlayfs, replacing aufs, there are new problems. Have worked through them, see recent blog posts; however, have not yet got direct-save to work. Attempting direct-save has brought with it the dreaded "cross-device link" error message, that I have complained about over the years. That error has kept me away from overlay, as aufs "just works". Or rather has just-worked until recently.
