@movitto Does it make sense to simplify this conditional by assuming if the 3rd argument is > 100, the number is a size, otherwise it's a percent?

```ruby
def self.create(name, vg, value)
  ...
  if value < 100
    params.merge!({'-l' => "#{value}%FREE"})
  else
    params.merge!({'-L' => bytes_to_string(value)})
  end
  ...
end
```
