you're not wrong but this is the way the code almost everywhere is currently doing w/o the err variable pre-declared. I personally like it over the changes you've made here :) but this is just my opinion.
some examples:
i.e.: https://github.com/docker/docker/blob/master/api/server/container.go#L107
i.e.: https://github.com/docker/docker/blob/master/api/server/container.go#L183

Sorry @runcom I have to disagree :) I prefer this PR, but it's all about different tastes :)

LGTM

@tiborvass no worry, it's all about different tastes as you said:)

LGTM

Thanks @runcom :)

I'm against, but whatever :) It reads worse.
