Thanks for the article to remember me of the existence of this project. I decided to do a setup in my home network using an old Raspberry Pi 1 that I had. Mainly because the router of my ISP screwed up really hard in its DHCP server, so I decided to disable it and use Pi-hole's one instead.

I tried to make this setup as robust as possible, using OverlayFS [1] so root is read-only unless I remount it (to change configuration or upgrades) and with a watchdog so it can auto-reboot in case my Raspberry Pi is unresponsive. Pretty happy with this setup and it my internet seems more responsible than ever.
