I started building "real" firmware for my raspi appliances using buildroot. That makes it super easy to build images that completely run from initramfs without a single write on the sd card (and are fully booted in a few seconds including userland).

Only works if I don't need any local persistence but makes the Pi just work super reliably. Upgrading is as easy as swapping the Linux Kernel image on the fat32 and rebooting.

cattlepi has the advantage of being able to essentially build and distribute images over the network + full raspbian.

on boot it self-updates if needed, builds on overlay filesystem w/ the squashed image as the bottom ro layer + tmpfs as top rw layer.

Thanks, cattlepi looks super interesting!
