[ydl-gen] PS3 Install with no DVD burner

[Steve Singer]

I installed Yellowdog on my PS3 last night without having to use a DVD 
burner and thought I'd share the steps.

- Download the iso mount it and make it available on a network share 
somewhere (local FTP/HTTP server, NFS etc...)
- Follow the normal steps in the docs to get GameOS to boot the installer 
and get to the 'kboot' point.
- Copy ppc/ppc64/vmlinux-ps3 and ppc/ppc64/ramdisk-ps3.image.gz to a USB 
memory stick.
-  On the ps3 type at the kboot prompt
    sh
    mount /dev/sdd1 /mnt/tmp (or whatever device your usb stick shows up as)
    cd /mnt/tmp
    /sbin/kboot vmlinux-ps3 initrd=ramdisk-ps3.image.gz text root=/dev/ram 
init=/sbin/init

This should reboot the ps3 in to the kernel on the USB drive and start the 
installer.  It should prompt your for an installation source and allow you 
to enter in a network configuration and the location that the YDL install CD 
is available at.


(I actually mounted my USB drive over /etc since I tried to modify the 
kboot.conf file but I don't think that is required)
