# The eland_import_hub_model script is intended to be executed by a shell,
# which will see its shebang line and then execute it with the Python
# interpreter of the virtual environment. We want to keep this behavior even
# with Wolfi so that users can use the image as before. To do that, we use two
# tricks:
#
#  * copy /bin/sh (that is, busybox's ash) from the builder image
#  * revert to Docker's the default entrypoint, which is the only way to pass
#    parameters to `eland_import_hub_model` without needing quotes.
