Let's Encrypt is going to a much shorter certificate lifetime. I think this is something home lab admins should start preparing for now. Especially if you have your scheduled tasks and CRON jobs configured for the current 90 day expirations. I put together a set of things to check if you are using tools like Certbot, Traefik, and reverse proxies to make sure you are ready. Also, I'm curious how you are handling certificate renewals and automation across your home lab. Are you using built-in ACME clients, Certbot, or something else?
