> I noticed a suspicious-looking world-readable file on a VM that talks to Google Compute Engine API via libcloud:
> {noformat}
> -rw-r--r-- 1 root root 164 Jun 27 21:21 .gce_libcloud_auth.wargame-engine
> {noformat}
> It contains a "Bearer" access token so presumably should not be readable by other users on a shared system. I suspect this (untested) patch might maybe fix this in git head:
> {noformat}
