Comment 1 for bug 1623003

Userspace rpm: udev
... Ubuntu does not use RPMs, do you mean .deb or just package?

Note the bugs are tracked by source package name, which is systemd.

This change was introduced upstream in v229 see:
https://github.com/systemd/systemd/blob/master/NEWS

https://github.com/systemd/systemd/commit/f073b1b3c0f4f0df1b0bd61042ce85fb5d27d407

https://lists.linuxfoundation.org/pipermail/virtualization/2015-August/030328.html

https://github.com/systemd/systemd/issues/2501

Please discuss this upstream to change/improve the path_id detection. This is not ubuntu-specific and affects all Linux on z that use systemd v229 or newer.

If a fix for this lands upstream, we can discuss cherrypicking it to xenial.
