This test plan assumes that you're using the mariadb daemon supplied as part of `nix develop`,
if you have mariadb installed through homebrew, then beware
that the nix supplied socket will be available at
$HOME/.local/share/MariaDB/mysql.sock as opposed to /tmp/mysql.sock.
In theory, this should work on linux and macOS, however, only tested and expected to be ran
on macOS.
```
# stop previous MariaDB
pkill mariadb
# Break some chain of assumptions, like removing the db config
rm -rf keyserver/secrets/db_config.json
nix develop # should emit that it's starting MariaDB and writing a config
cd keyserver
yarn dev # shouldn't crash when starting DB configuration
```
