# matrix-appservice-draupnir-for-all and matrix-bot-draupnir share the
# same upstream container image. When both are enabled and force-pull is
# on, the second role to run sees the image as already up-to-date (the
# first role just pulled it), so its pull_result.changed is false and
# conditional restart would skip it. To avoid that, we also treat
# force-pull itself as a restart trigger for this role. The downside is
# that both Draupnir services restart on every run when force-pull is
# enabled (e.g. with rolling tags like `latest` or `main`), even when the
# upstream image has not moved. That is wasteful but acceptable.
