# Generic

This bucket is never enabled by default. You have to enable it explicitly like
this:

```ruby
Vagrant.configure("2") do |config|
  config.cache.enable :generic, { :cache_dir => "/var/cache/some" }
end
```

The `:cache_dir` parameter is required. It specifies the directory on the guest
that will be cached under the "generic" bucket.

You may enable more than one generic bucket by giving them different names via
the `:name` parameter, like this:

```ruby
Vagrant.configure("2") do |config|
  config.cache.enable :generic, { name: "one", cache_dir: "/var/cache/one" }
  config.cache.enable :generic, { name: "two", cache_dir: "/var/cache/two" }
end
```

In this case you get two buckets called "generic-one" and "generic-two" under guest's
`/tmp/vagrant-cache`.

The Generic bucket is useful if you want to implement a caching mechanism by
hand. For instance, if you want to cache your wget downloads under
`/var/cache/wget` you can do this:

```ruby
Vagrant.configure("2") do |config|
  config.cache.enable :generic, { name: "wget", cache_dir: "/var/cache/wget" }
end
```

Then, you invoke wget like this:

```sh
wget -N -P /var/cache/wget URL
```
