When using myqsld --initialize to setup a new MySQL instance for MySQL 5.7.6 through 5.7.10, if the new instance is configured to have the InnoDB system tablespace and/or log files in a subdirectory of the data directory, the installation fails.

The error depends on whether the InnoDB directory is created before the attempt to initialize MySQL.
