Bug description:
[Impact]
NVMe drives can't be identified/accessed via /dev/disk/by-id/nvme-
SERIAL symlinks.
[Test Case]
On a system with an NVMe drive, check the /dev/disk/by-id/ directory;
with the patch, it will contain link(s) named by the drive serial
number. This should be the *only* change in `ls -l /dev/disk/*/*`.
On a system without NVMe, verify that `ls -l /dev/disk/*/*` is
identical (aside from dates, of course) before and after the upgrade
to the -proposed version.
[Regression Potential]
Errors in udev rules can lead to an unbootable or otherwise completely
broken system if they unintentionally break or clobber existing
/dev/disks/ symlinks.
[Other Info]
This patch is already included upstream and in zesty systemd.
