Title:
  (s)ata disks do not have /dev/disk/by-path links created

Status in systemd package in Ubuntu:
  Fix Released
Status in systemd source package in Trusty:
  Fix Committed

Bug description:
  [impact]

  udev (in trusty) does not create symlinks in /dev/disk/by-path/ for
  any disks that are connected via sata.

  [test case]

  Install trusty onto a system with sata drives, and check /dev/disk/by-
  path/ for symlink(s) to those sata drive(s).

  [regression potential]

  the (s)ata by-path symlinks were removed due to apparent possibility of 
non-uniqueness:
  https://git.kernel.org/pub/scm/linux/hotplug/udev.git/commit/?id=481dcf7c8f

  however that was *long* ago and it has been added back in:
  
https://github.com/systemd/systemd/commit/ba86822db70d9ffd02ad78cd02b237ff8c569c7a

  if there is still a possibility for non-uniqueness, then /dev/disk/by-
  path/ symlink(s) might be created that are non-deterministic as far as
  the actual disk/path they point to.

  [other info]

  this is 'fixed' (the by-path symlinks are created for ata disks) in
  Xenial and later systemd/udev.

  Also bug 1611945 indicates that sata devices connected via PMP (port
  multiplier device) may still have incorrect by-path symlinks created,
  even upstream.  However, since Xenial and later currently do have udev
  code that creates ata by-path symlinks, that is a separate issue and
  not a reason for keeping ata by-path symlinks about of trusty udev.
