Overview ¶
Package fsutil holds small filesystem helpers that refuse to follow symlinks. App directories can contain files that did not come from SimpleDeploy (git sync pulls, container bind mounts), so reads and writes of managed files (docker-compose.yml, .env, sidecars) must never be redirected to a path outside the app directory.
