PATH for Vagrant provisioners

[Ilya Dmitrichenko]

On Vagrant, trying to do this simple provisioning:

config.vm.provision "shell", inline: <<-SHELL
    echo PATH=$PATH
    snappy install docker
    docker pull errordeveloper/curl
SHELL

Results in:

==> default: stdin: is not a tty
==> default: PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/root/snappy-bin
docker 4 MB [==============================================] OK ]
==> default: Part Tag Installed Available Fingerprint Active
==> default: docker edge 1.3.3.001 - 60b98945e5fc1d *
==> default: /tmp/vagrant-shell: line 3: docker: command not found

So looks like the way PATH is set, it's would expect snappy to install packages in root's home, but he instals them in ubuntu's home.

I have no problem working around this, but it's just needs fixing. This happen to manifest itself on Vargant, but it's just a more general bug anyway.

The root cause is that the Vagrant user on Snappy is "ubuntu," not root.
So you will need to use "sudo" or switch to the root user. The root
user is not configured for SSH due to security issues, and as a result,
the provisioner will not work against root.

Setting to low as this appears (from Bens comment) to be mostly a documentation issue, i.e. ensure that "sudo" is used.
