> When run as root, {{TestCoreDiscovery.testCoreDirCantRead}} will fail.
> On some systems (I used CentOS 6.6) the call to set {{core1}} directory as unreadable will succeed, but the directory will still be readable by {{root}} user.
> Running unit tests as root is not a normal user case, but this was a single use EC2 instance that I created explicitly for some short-lived testing, so I didn't bother creating specific users.

> We should change the earlier {{assume}} to be more robust.
