The modification of the flake.nix file is just removing the mariadb v.10.8 overlay, automatically bumping us to v.10.11.
The mariadb-up script is also modified to check whether or not an upgrade is necessary. If required, it will run `mariadb-upgrade`.
For a dev currently on 10.8, after this is landed, the dev will
1. pull the commit
2. exit their terminals and any `nix develop` sessions
3. pkill mariadb` if there is a running server process (`ps aux | grep mariadb`)
4. nix develop
On this nix develop, it should identify an upgrade is required and print out upgrade progress
After this step, everything should be upgraded
If the dev has important information on their local keyserver that they want to ensure is backed up, they can run through Inka's backup documentation:
