Bug with minimize.sh (Ubuntu 14.04 amd64)

[guilliman]

This is normal behavior or a bug yet?

==> virtualbox: Provisioning with shell script: scripts/minimize.sh
    virtualbox: dd: error writing `/EMPTY': No space left on device
    virtualbox: 3345+0 records in
    virtualbox: 3344+0 records out
    virtualbox: 3506683904 bytes (3.5 GB) copied, 22.9182 s, 160 MB/s

script:

#!/bin/sh -eux

dd if=/dev/zero of=/EMPTY bs=1M
rm -f /EMPTY
# Block until the empty file has been removed, otherwise, Packer
# will try to kill the box while the disk is still full and that's bad

You're talking about the "dd: error writing '/EMPTY'" message, right? This is normal behavior as the idea is to fill up the remaining disk with zeroes and then delete it.
