Downloading a Debian root filesystem

This note is mainly for my own benefit but might be handy for others too.

Whenever I want an ad hoc Debian root filesystem to build and test my software on a mainstream consumer Linux distribution, I am frustrated by my struggle to find and download one.

Search engines turn up lots of documentation, but everything seems to involve weird Debian-specific tooling like debootstrap. Please stop!

Quick wireguard tunnel setup

This is a simple point-to-point tunnel between two hosts with no address restrictions on traffic routed through it. Fixed link-local addresses of fe80::1 and fe80::2 are assigned to the endpoints, suitable for running RFC 5549 link-local BGP.
