Prompt Original prompt

Exact prompt as published in the source.

This is a Datasette plugin which should add a new page /-/os which returns pretty-printed JSON about the current operating system - implement it. I want to pick up as many details as possible across as many OS as possible, including if possible figuring out the base image if it is in a docker container - otherwise the Debian OS release name and suchlike would be good
