Quite some time has passed since I rented my first vServer (running Debian Squeeze), and over the years I dist-upgraded twice and accumulated lots of baggage. There are custom init scripts (nowadays systemd units), executables whose purpose I can’t remember and several databases (I guess at least MySQL, Redis and etcd). There are backup directories of my wife, which hold dear pictures and videos of our daughter. My web stack is a confusing combination of lighttpd, a letsencrypt cron job, wild php-cgi appearances and some obscure python scripts using http.server. I tried accessing my blog a couple of days ago and was greeted by a nice 503 error message. This was the point where I knew I need to change something.
