Change the location for config autosave

Describe you feature request

I am running frankenphp in a docker built with our own Dockerfile (Ubuntu 22.04).

Since frankenphp is running as nobody, it is trying to write files to nobdy's home directory: /nonexistent. Is there a way to change this location in Caddyfile? Thanks!

Why not just change nobody's home folder?

env HOME=/my/home/folder

or

RUN usermod -d /new/home/directory nobody && chown -R nobody /new/home/directory

I have tried this workaround and got the Caddyfile autosave config. It helps greatly to know the setting snapshot. Thanks!
