NetBSD x1.glob.io 6.1.5 NetBSD 6.1.5 (GENERIC) amd64
>Description:
The lfs_renamerace_dirs test case fails when running the test suite on a fresh install performed using sysinstall. The error "No space left on device" does not appear to be accurate as each machine has large amount of free disk space and memory. I can reproduce these failures on 2 different amd64 machines.

Note that I will create a separate PR for the lib/librumphijack/t_tcpip:http error below.

Perform an amd64 install, reboot and run the test suite described by tests(7) either as root or another user.
