Confine a custom fact by file existence

[Thomas Müller]

Hi

I know it's possible to confine a fact by other facts like "confine :operatingsystem => :Fedora". 

But i have a fact which requires a binary from a rpm package which is only installed by puppet. For the first puppet run tries to execute the not-yet installed binary and fails.

is it possible to use something like this to confine based on existing files?

confine File.exists?(/path/to/binary)

Or what is the best practice for such facts which rely on things installed by puppet manifests?

Why, yes, but the syntax is:

confine :exists => "/path/to/binary"

, as documented among the provider development documentation.

Facter, not providers, John. Those are, sadly, different beasts.

It is possible, as the `confine` method also takes a block:

```

Facter.add(:foo) do

  confine do

    File.exist? '/path/to/binary'

  end

  setcode do

    'bar'

  end

end

```

 

confine File.exists?(/path/to/binary)

Or what is the best practice for such facts which rely on things installed by puppet manifests?
