See my other reply. You added additional PCI bridge(s) which caused
all subsequent numbers to be shifted. Basically the same case as
having /dev/sda becoming /dev/sdb after adding disk.

Note that *tree* path actually remains persistent, in all cases it is
0000:00 - 1c.4 - 00.0, but unfortunately it is not what is used to
identify device.

OTOH I suspect the answer from upstream would be "we do not guarantee
persistence if hardware configuration changes".

But wasn't this the main promise of "predictable" naming?


I do not know about "main" but reviewing
http://www.freedesktop.org/wiki/Software/systemd/PredictableNetworkInterfaceNames/
it does promise "Stable interface names even when hardware is added or
removed" so this makes it topic for upstream bug report.


Thanks for the link. The primary objective seems to be that the interface names remain constant from boot to boot even when parallel probing.

With my single interface I'm going to leave upstream and switch back to persistent following the hints in this thread.
