### Using VirtualBox for development
### Using `vagrant-lxc` to develop itself
I've also prepared a Vagrant 1.0 VirtualBox machine for development that you can
get up and running with the [`setup-vagrant-dev-box`](setup-vagrant-dev-box)
script. Feel free to use it :)
Yes! The gem has been [bootstrapped](http://en.wikipedia.org/wiki/Bootstrapping_(compilers)
and since you can boot a container from within another, after cloning the
project you can run the commands below from the host machine to get a container
ready for development:
```sh
bundle install
cd development
cp Vagrantfile.dev.lxc Vagrantfile
# Required in order to allow nested containers to be started
sudo apt-get install apparmor-utils && sudo aa-complain /usr/bin/lxc-start
./setup-lxc-dev-box
```
That should result in a container ready to be `bundle exec vagrant-lxc ssh`ed.
Once you've SSH into the guest container, you'll be already on the project's root.
Keep in mind that you'll probably need to run `sudo aa-complain /usr/bin/lxc-start`
on the host whenever you want to hack on it, otherwise you won't be able to
start nested containers there to try things out.
### Using VirtualBox and Vagrant 1.0 for development
```
cp Vagrantfile.dev.1.0 Vagrantfile
./setup-vagrant-dev-box
vagrant ssh
cd development
cp Vagrantfile.dev.vb Vagrantfile
vagrant up
```
