# Also make sure that instance/static/emoji exists.
# Pleroma does not ship with an `instance` folder by default, causing docker to create `instance/static` for us at launch.
# In itself that wouldn't be much of an issue, but said folder(s) are created as root:pleroma with 2755.
# This breaks the custom.d step in entrypoint.sh which relies on writing there (See #10).
