As a record, if magnum team doesn't interest to maintain the CoreOS driver,
it is an indication that this driver should be spitted out and maintained
by another team. CoreOS is one of the prevailing container OS. I believe
there will be a lot of interests after the split.

Disclaim: I am an author of the CoreOS driver

Best regards,
Hongbin
