Author: glen
Date: Tue Jan 17 23:11:27 2006
New Revision: 6838

Modified:
   geninitrd/trunk/geninitrd
Log:
- add dmraid support, needs udev as it creates nodes on /dev
- probably udev support should be improved to copy config to initrd so the 
nodes correspond to ones configured in host
  currently customised udev in host has no effect on initrd
