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:/
however that was *long* ago and it has been added back in:
https:/
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.
