I know. Shall I leave them off for the time being or shall I
coordinate with Mike for a naming convention ?
I'll be working on this on and off throughout today. I've got as far
as the build system attempting to build the library which I expect
will be called librumpdev_nvme. I don't yet know if ld_nvme.c and
nvme.c can be linked in the same library for our purposes which would
keep things simpler.

I've made a little progress. This is the output from rumpdisk boot when
linked with some new Nvme/ld rump libraries:

I'm not attempting to open the device yet as that will need the
forthcoming changes to rumpdisk code.
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.
Mike.
