### Avoiding `sudo` passwords
This plugin requires **a lot** of `sudo`ing since [user namespaces](https://wiki.ubuntu.com/UserNamespace)
are not supported on mainstream kernels. In order to work around that we can use
a really dumb **AND INSECURE** Ruby wrapper script like the one below and add
a `NOPASSWD` entry to our `/etc/sudoers` file:
```ruby
#!/usr/bin/env ruby
exec ARGV.join(' ')
```
For example, you can save the code above under your `/usr/bin/lxc-vagrant-wrapper`,
turn it into an executable script by running `chmod +x /usr/bin/lxc-vagrant-wrapper`
and add the line below to your `/etc/sudoers` file:
```
USERNAME ALL=NOPASSWD:/usr/bin/lxc-vagrant-wrapper
```
*__WARNING__: the `/usr/bin/lxc-vagrant-wrapper` + `/etc/sudoers` combination
above allows `USERNAME` to run any privileged command without a password. You
might want to think twice before using that on a machine with sensitive data.*
In order to tell vagrant-lxc to use that script when `sudo` is needed, you can
pass in the path to the script as a configuration for the provider:
```ruby
Vagrant.configure("2") do |config|
config.vm.provider :lxc do |lxc|
lxc.sudo_wrapper = '/usr/bin/lxc-vagrant-wrapper'
end
end
```
If you want to set the `sudo_wrapper` globally, just add the code above to your
`~/.vagrant.d/Vagrantfile`.
are not supported on mainstream kernels. Have a look at the [Wiki](https://github.com/fgrehm/vagrant-lxc/wiki/Avoiding-'sudo'-passwords)
to find out how to work around that specially if you are running an OS with sudo
< 1.8.4 (like Ubuntu 12.04) as you might be affected by a bug.
