Hopefully fixed cp for osx.

Works once. Fails on the second run.

pnpm master » npm i           

> pnpm@0.0.1 install /Users/z/code/forks/pnpm
> cp -n config.json.template config.json

pnpm master » npm i

> pnpm@0.0.1 install /Users/z/code/forks/pnpm
> cp -n config.json.template config.json

Using the following snippet has the same effect. Works once, then fails.

[[ config.json.template -nt config.json ]] && cp config.json.template config.json

Ah, right exit values– I'm not surprised the snippet failed. You'd suppress that with:

[[ config.json.template -nt config.json ]] && cp config.json.template config.json || true

I am surprised that cp -n doesn't return success when it doesn't do anything, but you should be able to suppress it the same way:

cp -n config.json.template config.json || true

@zeke Does this work for you?
