Following the convention used by other scripts in this repo (chef.sh/cvmfs.sh/termux.sh) — they all dereference TUNASYNC_WORKING_DIR directly and rely on the tunasync framework to set it. Keeping consistent with that.


exec "$mirror_clone" \
--target-type file \
--file-buffer-path "${TUNASYNC_WORKING_DIR}/.tmp" \
--file-base-path "${TUNASYNC_WORKING_DIR}" \
$TUNASYNC_MIRRORCLONE_OPTIONS \
"$TUNASYNC_MIRRORCLONE_SOURCE" \
$TUNASYNC_MIRRORCLONE_ARGS

The unquoted expansion is intentional: it lets per-mirror configs pass multiple positional flags through TUNASYNC_MIRRORCLONE_OPTIONS / TUNASYNC_MIRRORCLONE_ARGS. Switching to bash arrays would change the public interface (existing tunasync mirror configs would have to be rewritten). Keeping current behavior.
