Sparc beta 3 CD images have the wrong silo.conf

[Peter Karbaliotis <peter.karbaliotis@ualberta.ca>]

VFS: Cannot open root device "" or 00:00
Please append a correct "root=" boot option
Kernel panic: VFS: Unable to mount root fs on 00:00
  Press L1-A to return to the boot prom

Booting with "linux root=/dev/rd/0 devfs=mount,dall rw" works.

The silo.conf on the beta 3 CD images does not have the boot options to 
turn on devfs and set root to the ramdisk devfs device.

Here is the silo.conf from the cdrom-mini.iso

partition=1
timeout=600
read-only
message=/boot/debian.txt
default=linux
initrd=/boot/initrd.gz
root=/dev/rd/0
