No, it's not that simple.
The kernel and anything is free to use the naming policy it wants, but
that's not the problem here. p* is still used in nvme, but there is a
numbering before that for the device ID -- nvme0n1 points to a "drive",
nvme0n1p1 points to a partition. This issue is in grub-installer, it's
just that I don't have NVMe drives to play with to figure it out.
Could someone seeing this issue please run the installer but just before
that, modify grub-installer to add "set -x" near the top so we can see
which part of grub-installer does the parsing wrong?
Reassigning to grub-installer since we don't need to bug the kernel team
for this...

Bug description:
On T460s, I tried to install the wily daily build, it could detect
the nvme partition, at the end of installation, it prompt ' Unable to
install GRUB in /dev/nvme'

Why it install to /dev/nvme, while not the /dev/nvme0n1?
$ sudo grub-install --boot-directory /target/boot/grub /dev/nvme

grub-install: error: cannot find a GRUB drive for /dev/nvme. Check your
device.map.
$ sudo grub-install --boot-directory /target/boot/grub /dev/nvme0

$ sudo grub-install --boot-directory /target/boot/grub /dev/nvme0n1

Inatalltion finished. No error reported.
But even it's no error reported, I still cant' find any grub after
reboot.
