What do you mean where is ?
Why should lainchan run a GNU social instance ?
How is this supposed to augment the existing services ?
Looking into the path to implementation further, it looks like the existing docker implementation is soykaf (e.g. the configuration of the docker container isn't what the author actually runs on their site), and I would have to rewrite a new dockerfike and docker-compose file that either played with the existing containers or was entirely self contained.
>Why not use the tokumei?
Because it is written in plan9 shell e.g. rc, and that makes it difficult to maintain.
