+## Storage/SPOT
+
+the papermc container already copies all files in /mnt/*
+to /data, so it's easy to add overwrites.
+in ./lobby.nomad.hcl I just use a prestart container that downloads the plugin
+to a temporary volume that is then used as /mnt.
+A lot of boilerplate and it's also not easy to add other files.
+Ideally, we'd just copy a whole directory over sftp. it would look
+like this:
+    /.gitignore <- data
+    /Makefile <- downloads plugins specified to /data/plugins
+    /static <- static files that are copied by make to /data
+But ig that wouldn't play nice with CI/CD...
+
+Also currently we need to duplicate a lot of this boilerplate btw.
