¡Hola!
Estoy en la revisión 136a5456534c7e468b8052f865ce970a3bf375e9, donde ejecutar multisite:migrate falla con:
I, [2020-05-07T06:57:21.288947 #1] INFO -- : > cd /var/www/discourse && sudo -Eu discourse bundle exec rake multisite:migrate
`/root` no es escribible.
Bundler usará `/tmp/bundler20200507-300-1g5pu90300' como tu directorio principal temporalmente.
rake aborted!

Parece que esto está relacionado con la manipulación de middleware en config/initializers/200-first_middlewares.rb.
Volver a la versión anterior a 136a5456534c7e468b8052f865ce970a3bf375e9, el commit que actualiza a Rails 6.0.3, permite que multisite:migrate funcione. También tengo una instancia de desarrollo en la que he reemplazado session_operations con .delete y .unshift en Rails.configuration.middleware, y parece estar satisfecho con el resultado.
(… salvo la migración 20141216112341_resolve_duplicate_group_names que falla, alegando una columna inexistente groups.automatic_membership_email_domains, pero eso desaparece al reintentar.)
He olvidado casi todo lo que solía saber sobre Rails, ¡así que podría estar completamente equivocado aquí!
