At which place?

That leads to similar problems as "udev": I have to define on another
place ("/lib/udev/devices") the desired device.

That seems to be the behaviour I'm watching on my test machine. "hard
coded" device with 10:55, but the system uses 10:234
If btrfs is designed to work only under udev then it has to check wether
udev is running.
Viele Gruesse!
