Comment 28 for bug 1726818

I have validated that / file system size becomes 9.7GB
after using `-proposed` option as suggested.

# Steps to validate

- At Vagrant host
$ vagrant init ubuntu/artful64
$ vagrant ssh

- At Vagrant guest without `-proposed`

vagrant@ubuntu-artful:~$ df -h /
Filesystem Size Used Avail Use% Mounted on
/dev/sda1 2.2G 1.3G 862M 60% /

-
$ sudo vi /etc/apt/sources.list and add the following entry.
```
deb http://archive.ubuntu.com/ubuntu/ artful-proposed restricted main multiverse universe
```

$ sudo apt-get update
$ sudo apt-get upgrade
$ sudo reboot

$ vagrant ssh
vagrant@ubuntu-artful:~$ df -h /
Filesystem Size Used Avail Use% Mounted on
/dev/sda1 9.7G 1.4G 8.4G 14% /

Thank you for the fix.
