Creating udev stages would require a separate profile which would be
removed once we did the default switch, so I'm not sure if we want to go
that route. Does anyone remember if we did this for the original eudev
switch? If we did, I am open to doing it again, but I honestly don't recall.

All of the providers are stable currently, so my thought is a tracker +
newsitem with a delay before switching the default. I'm thinking about a
30 day test window where we ask people to migrate their systems and
if they find issues open bugs that block the tracker.

Thoughts?
