Indeed, that’s part of the problem.

Another example: our cerbot service offers a ‘deploy-hook’, but the
/gnu/store/… file name of that hook gets recorded somewhere in
/etc/letsencrypt and thus becomes invalid once the hook has been GC’d or
the system has been reconfigured.

Yeah, I think anyone running a web server on Guix System gets hit by
this issue.  I’m not super knowledgeable about certbot either so I tend
to just hack around to get things to work, which is not great.
