Description of problem:

I get error message:

Error: Not enough space in /boot/upgrade to download install.img.

The installer can download this file once it starts, but this requires a wired network connection during installation.

If you do not have a wired network connection available, you should quit now.
Traceback (most recent call last):

Version-Release number of selected component (if applicable):
This is F10 on a server, trying to upgrade to F11 server. 64bit hardware and 64bit software.



Additional info:
seems to be related to the virtual RAID. I remember I had a RAID-related problem with preupgrade when upgrading from F9 to F10. The upgrade from F10 to F11 gave me now problems at all. Maybe an old RAID-related problem with preupgrade that crops up again?
