[systemd-devel] Persistent virtio device name removal

[Michael Marineau]

Working on bumping to 215 over here in CoreOS land, but I've got a
question regarding the removal of persistent device names for virtio
devices since changing the network device names creates a difficult
upgrade path from 212. The commit was:

http://cgit.freedesktop.org/systemd/systemd/commit/?id=bf81e792f3c0aed54edf004c1c95cc6f6d81d0ee
"udev: persistent naming - we cannot use virtio numbers as they are not stable"

The commit doesn't say what the issue was, in what situations are the
virtio numbers not stable?

Thanks,
Mike
