Seems that one Travis test exited with a weird error, most probably unrelated to the pull request:

The other three seem fine.

@prusnak LGTM. i think needs a test to make sure we dont add regressions. (see the sharness tests. just make a new file, probably based on the repo one, or init or daemon. and test the initial state after initing with the option.

Here is a test I wrote for this:

@prusnak and @jbenet what do you want to do on this?
@prusnak feel free to cherry pick the commit that contains the test and push it into this branch.
Otherwise I can also create a PR from the empty-repo branch on my fork (https://github.com/chriscool/go-ipfs/commits/empty-repo).

[jbenet]

the PR LGTM. +1 to having tests before merging it. whoever does it first, wins a ⭐
