I got a freebsd system and I successfully modified cd image so it uses usb  
stick to write config file.
But there is a problem, when booting it stucks at:
waiting 15 sec for scsi devices to settle down.

I'm using a fat32 fs on usb stick. Is this a problem? If so, which  
filesystem should I use then?
