--cfg doesn't work

[Stebalien]

The related code in IpfsInit is commented out.

@whyrusleeping was that a mistake or did this never work?

Hm, from what I can tell the option to override the default IPFS config isn't supported right now (the codebase has changed a lot since then). Is that right @travisperson, @frrist? Do we still want this?

Ya, this feature was stripped out when we made iptb more generic. There is currently a Config interface that works on an interface{}, though maybe this should be a string / byte slice and allow the plugin to encode / decode.

iptb/testbed/interfaces/node.go

Lines 35 to 41 in 081be46

	type Config interface {
	Core
	// Config returns the configuration of the node
	Config() (interface{}, error)
	// WriteConfig writes the configuration of the node
	WriteConfig(interface{}) error
	}
