+#### Skip find and chown
+
+By default, the container checks permissions on `/data` to ensure the `plone` user can write to it.
+On large datasets, this `find` command can take a long time.
+If you are confident that permissions are correct, set `SKIP_FIND_AND_CHOWN` to any value to skip this step and speed up startup.
