I can install and run pixelfed on a subdomain, for example, pixelfed.example.com. However, I also run mastodon.example.com. My webfinger points at mastodon. How do I configure a webfinger for both pixelfed and mastodon? How do you all have your webfingers setup when you run multiple activitypub-based services?

Edit: I should also add that I'm trying to tie my mastodon account to user@domain.tld, not specific to the mastodon subdomain, but specific to my user email identity. My mastodon domain would be sometime like mastodon.domain.com, which would normally make my user user@mastodon.domain.com.

I do see this as a potential solution - I could route the specific service based on user agent to the correct webfinger: https://serverfault.com/questions/775463/nginx-redirect-based-on-user-agent#825725

So here is the issue on github:

If folks have GitHub accounts, could you please bump this/thumbs up?
