I'm not attempting to open the device yet as that will need the

It took me quite a while to work out how to add an Nvme device within
my libvirt/Qemu setup but I hope that the above suggests that a
logical disk is being detected even though there are errors within the
module init for ld. It is a more significant task than I expected
although these things often are. I've a feeling that there will need
to be quite a few new rump libraries built as there are a number of
'ld_xxx' modules that presumably relate to specific devices. I've
almost had enough for today but will give it some time tomorrow.

I haven't yet made any calls to rump_vfs_makedevnodes() so it's perhaps
inaccessible at the moment. It's a start anyway.
Mike.
