- Downloads a portable MariaDB (doesn't pollute your main system)
- Sets up a database with a random password on port 1338 (configurable)
- Installs the initial schema
- Every time after, will run updates

Major versions right now explicitly escape hatch, because those
historically come with something like a Python script, and I do not want
it to pretend to work.
