lolcathost.org is a Fediverse instance that uses the ActivityPub protocol. In other words, users at this host can communicate with people that use software like Mastodon, Pleroma, Friendica, etc. all around the world.
This server runs the snac software and there is no automatic sign-up process.
How would you replicate the underlying data store between those 3 instances without running into corruption issues on the fs level?
This is just a test with this hilarious domain name registered by @pancake@lolcathost.org a long time ago.
