-# Start the rootless Docker daemon in the background.
-# The `docker:dind-rootless` image's default `ENTRYPOINT` is `dockerd-rootless.sh`.
-# Since we are overriding the ENTRYPOINT with `start.sh`, `start.sh` must explicitly
-# run `dockerd-rootless.sh`.
-# We use `exec` here so that `dockerd-rootless.sh` becomes the main process,
-# allowing it to correctly set up the rootless environment and `rootlesskit` re-execution.
-# We then put it in the background and wait for it.
-
-# IMPORTANT: The `dockerd-rootless.sh` script itself uses `exec rootlesskit ... $0 $@`
-# This means it replaces the current shell process.
-# So, we cannot simply run it with `&` and expect the rest of `start.sh` to execute.
-# Instead, we need to manage the daemon's lifecycle differently.
-
-# Let's try to run dockerd-rootless.sh directly as the primary process,
-# and then use a separate mechanism to run our build/run commands.
-# This is problematic for a single CMD/ENTRYPOINT.
-
-# Alternative approach: Run dockerd-rootless.sh in the background, but use a loop to wait for its socket.
-# This is the most common pattern for DinD when you need to run other commands.
