Well, it points to something a bit different than that, but that's not
really germane.

The lack of the initrd.img file in the specified location will cause
OFW to print an error message, and then carry on giving control to the
linux kernel.  So unless the kernel needs the initrd (in the case, it
doesn't), you don't have to worry about it.

There's no livecd-to-usb script involved.  There is no overlay
involved either.

Ok.  So the instructions should be:

1) Power on the XO-1 with the USB stick in it
2) Press Esc to get to the OFW prompt
3) Check the USB stick looks ok with "dir u:\boot"
4) Boot from the USB stick with these OFW commands:

" ro root=LABEL=OLPCRoot rootwait" to boot-file
" u:\boot\vmlinuz" to boot-device
setup-smbios
boot

Then it'd be good to observe what happens. Do you see the green and
blue "sugarlabs" logo when the kernel messages appear?

They're good to have in normal operation but are not required to get
to a basic runlevel 3 or 5.
