# Seed app.ini into the writable config volume (/etc/gitea) from the read-only swarm config
# (mounted at app.ini.init). Gitea persists settings back to app.ini — e.g. it saves the
# [oauth2] JWT_SECRET on boot since 1.24 — which crashes if app.ini is the read-only mount itself.
# Test `! -s` (empty), not `! -f` (missing): upgrades from the old direct-mount layout leave a
# 0-byte app.ini placeholder that still needs seeding. A non-empty app.ini is left untouched.
