I know we've talked about this over and over and another bug [1] reminded me of it. We have long talked about removing the ability to specify a block device name when creating a server or attaching a volume because we can't honor the requested device name anyway and trying to do so just causes issues. That's part of the reason why the libvirt driver stopped honoring the block device name in requests back in Liberty [2].

I think we all agree on removing the device name from the API, but I'm having a hard time remembering if someone signed up to write a spec for this. I could have sworn this came up recently and someone said they'd write a spec, but I can't remember.

So this is my attempt at remembering and if it's all a dream, then is anyone interested in owning this? If not, I'll start writing the spec this week.
