# ephemeral-disk-warning - warns user that the disk is really, really ephemeral
#
# On Azure, the ephemeral disk is extremely ephemeral; the ephemeral disk is
# unsafe between boots. This places a file on /mnt that warns the user
# that the disk is a dangerous place for storing data of any importance.
