#
# We want to update the user through the pipeline, but the ActivityPub
# update information is not quite enough for this, because this also
# contains local settings that don't federate and don't even appear
# in the Update activity.
#
# So we first build the normal local changeset, then apply it to the
# user data, but don't persist it. With this, we generate the object
# data for our update activity. We feed this and the changeset as meta
# inforation into the pipeline, where they will be properly updated and
# federated.
