Any scripts in the ``scripts/per-instance`` directory on the datasource will
be run when a new instance is first booted. Scripts will be run in alphabetical
order. This module does not accept any config keys.
Some cloud platforms change instance-id if a significant change was made to
the system. As a result per-instance scripts will run again.
