[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.
