"""Runtime smoke test for the Docker tini compatibility shim (#34192, #66679).

Regression for #34192 / #66679: orchestration templates (e.g.

Hostinger's 'Hermes WebUI' catalog, NAS compose projects that keep
|
|
an old entrypoint across image updates) still pin /usr/bin/tini as
|
|
the entrypoint, often with ``-g --``. A missing shim fails to exec; a
|
|
bare symlink to /init forwards ``-g`` into s6 and boot-loops. The shim
|
|
must strip the tini flags and hand the remaining args to /init +
|
|
main-wrapper, so the requested command runs normally.
