Simplify boot storage

You are right. I meant  `Array(names).each`:
```ruby
irb(main):001:0> s = "foo"
=> "foo"
irb(main):002:0> s.to_a
NoMethodError: undefined method 'to_a' for "foo":String
irb(main):004:0> s.to_ary
NoMethodError: undefined method 'to_ary' for "foo":String
irb(main):005:0> Array(s)
=> ["foo"]
irb(main):006:0> Array(Array(s))
=> ["foo"]
```
