"""This profile demonstrates how to add some extra *local* disk space on your
node. In general nodes have much more disk space then what you see with `df`
when you log in. That extra space is in unallocated partitions or additional
disk drives. An *ephemeral blockstore* is how you ask for some of that space to
be allocated and mounted as a **temporary** filesystem (temporary means it will
be lost when you terminate your experiment).

Instructions:
Log into your node, your **temporary** file system in mounted at `/mydata`.
