I think patch is ready. Robert Muir, are you fine with the new test using 
symlinks?
{quote}

The check is wrong. It can actually work on windows if you have system privs to 
do it, among other reasons. Please do it like this:
{code}
try {
  Files.createSymbolicLink(x, y);
} catch (UnsupportedOperationException | IOException e) {
  assumeNoException("test requires filesystem that supports symbolic links", e);
}
{code}

> NVMe is the faster (than AHCI) protocol for newer SSDs that plug into the 
> PCIE bus.
> I just built a new beast box with one of these drives, and the partition is 
> named {{/dev/nvme0n1p1}} while the device is {{/dev/nvme0n1}} by Linux - this 
> also appears in /sys/block with rotational=0.
> I think [~steve_rowe] also has an NVME drive ...
> [~thetaphi] (who got the box working for me: thank you!!!) has ideas on how 
> to fix it!
