`--entrypoint`.
In order to avoid a situation where commands are run without clear visibility
to the user, make sure your script ends with something like `exec "$@"`. After
the entrypoint completes, the script will transparently bootstrap the command
to the user, make sure your script ends with something like `exec "$@"` (see
[the exec builtin command](http://wiki.bash-hackers.org/commands/builtin/exec)).
After the entrypoint completes, the script will transparently bootstrap the command
invoked by the user, making what has been run clear to the user (for example,
`docker run -it mysql mysqld --some --flags` will transparently run
`mysqld --some --flags` after `ENTRYPOINT` runs `initdb`).
