[Bug 1642903] Re: introduce disk/by-id (model_serial) symlinks for NVMe drives

[Launchpad Bug Tracker]

This bug was fixed in the package systemd - 229-4ubuntu13

---------------
systemd (229-4ubuntu13) xenial; urgency=medium

  [ Martin Pitt ]
  * Backport graphical-session{,-pre}.target user units, for future usage from
    snaps. (LP: #1640293)
  * debian/rules: Clean up *.busname units. They are useless in 16.04 as they
    will always be "condition failed" as kdbus has never existed. But they add
    ordering constraints which make it impossible to start
    systemd-networkd.service during early boot, which is an upcoming
    requirement for cloud-init. (Part of LP: #1636912)
  * Drop systemd-networkd's "After=dbus.service" ordering so that it can start
    during early boot (for cloud-init.service). It will auto-connect to D-Bus
    once it becomes available later, and transient (from DHCP) hostname and
    timezone setting do not work in 16.04 anyway. (LP: #1636912)

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.
