- The `sudo_wrapper` provider configuration was removed in favor of using the
secure wrapper generated by `vagrant lxc sudoers` [[GH-272]]
- Support for specifying backingstore parameters from `Vagrantfile`s for `lxc-create`
was added and it defaults to the `best` option. On older lxc versions that does not
support that value, it needs to be set to `none`.

### Backingstore options
Support for setting `lxc-create`'s backingstore option (`-B`) can be specified
from the provider block and it defaults to `best`, to change it you can:
```ruby
Vagrant.configure("2") do |config|
config.vm.provider :lxc do |lxc|
lxc.backingstore = 'none' # or 'btrfs', 'lvm', ...
end
end
```
For old versions of lxc (like 0.7.5 shipped with Ubuntu 12.04 by default) that
does not support `best` for the backingstore option, changing it to `none` is
required and a default for all Vagrant environments can be set from your
`~/.vagrant.d/Vagrantfile` using the same `provider` block above.
### Avoiding `sudo` passwords
This plugin requires **a lot** of `sudo`ing since [user namespaces](https://wiki.ubuntu.com/UserNamespace)
