Sounds logical. And also works in a quick piuparts test.

What surprises me is the changelog entry for 2.02.64-1:
  * Enable udev sync, remove explicit udev dependency, bump dmsetup dependency
    to get it working. (closes: #543163)

The question is if udev is necessary; if not it probably can be moved
from Default-Start to Should-Start in the init script.
 
I've also tried this and it also works.
